Notes and Proof of the Intoxilyzer 8000 has Flaws with Proven Cases



In many cases, the VNM reading showing a result over a .08 is not admissible at the DUI trial:

“In cases where the Intoxilyzer 8000 registered a reading or readings of “volume not met,” however, it appears that the circuit courts have routinely concluded that such a reading was unreliable and, therefore, not valid. See Department of Highway Safety & Motor Vehicles v. Cherry, 91 So. 3d 849, 856-57 (Fla. 5th DCA 2011).

— See Kenyon v. Dep’t of High. Saf. & Motor Veh., 16 Fla. L. Weekly Supp. 899a (Fla. 4th Cir.Ct.2009) (“The machine produced a print-out that read “volume not met” which means that Petitioner was not providing a sufficient amount of breath in order for the machine to produce a valid test result.”)

— Underwood v. Dep’t of High. Saf. & Motor Veh., 15 Fla. L. Weekly Supp. 299a (Fla. 4th Cir.Ct.2008) (“The printout from the machine established that both of the samples given by Petitioner were designated as ‘Volume Not Met,’ and the machine indicated that because of this, both samples were not reliable to determine breath alcohol level”)

— Saladino v. State of Florida, Dep’t of High. Saf. & Motor Veh., 15 Fla. L. Weekly Supp. 222a (Fla. 12th Cir.Ct.2008) (“The Petitioner submitted two breath samples, but the results for both indicated ‘volume not met,’ meaning the samples were insufficient to determine Petitioner’s breath alcohol level.”).”

section 316.1932(1)(f)3., Florida Statutes
[Ms. Cherry] cites the case Unruh v. State, 669 So.2d 242 (Fla.1996) where the Florida Supreme Court held that law enforcement officers are required to render reasonable assistance

Rule 11D-8.002(12), Florida Administrative Code (2010). Rule 11D-8.002(12) states that failure to provide the required number of valid breath samples constitutes a refusal to submit to the breath-alcohol test.

Rule 11D-8.002(13) [sic] and regulated by section 316.1932(1)(a)2., Florida Statutes. The breath-alcohol test administered on [Ms. Cherry] was made in substantial conformity with the applicable administrative rules and statutes, Dep't of Highway Safety & Motor Vehicles v. Russell, 793 So.2d 1073 (Fla. 5th DCA 2001). Although a majority of the cases cited by [Ms. Cherry] are not controlling in this Circuit, they are persuasive because they are very similar factually to the instant case. See Mulligan v. State, 9 Fla. L. Weekly Supp. 146a (Fla. 7th Cir.2002); Wolok v. DHSMV, 1 Fla. L. Weekly Supp. 204a (Fla. 11th Cir. 1992); and Burson v. Collier, 226 Ga. 427, 175 S.E.2d 660 (Ga.1970). 

The Supreme Court of Georgia in Burson held that suspending a person's driver's license greatly hinders that person's use and enjoyment of an item of that person's personal property and thus, the statute providing the authority for the license suspension should be strictly construed. When statutes do not explain what constitutes a "complete" breath-alcohol test, a showing that a person did not complete the test (within the judgment of the operator) is not evidence of a refusal to submit to a breath-alcohol test within the contemplation of the statute. To consider this information as evidence, would provide the operator with an unfettered right to determine what is and what is not a complete test. Burson, 175 S.E.2d at 662.

In the instant case, the applicable Florida Statutes under chapter 316 and 322 do not explain what constitutes a "complete" breath-alcohol test. The breath technician and Trooper Hooker decided to determine an "implied refusal" after the second breath-alcohol test time frame. The Department's argument that the samples are invalid solely because [Ms. Cherry] did not perform the test to the breath technician's satisfaction is not persuasive. To apply the Department's argument could open the door to a pattern of providing breath technicians and law enforcement officers with unrestrained power when determining what is and what is not a complete test.  

Therefore, a showing that [Ms. Cherry] did not complete the test (within the judgment of the breath technician) should not be considered as evidence of a refusal to submit to a breath-alcohol test within contemplation of the statutes. 

Accordingly, the Department failed to meet its burden as to the required element under section 322.2615(7)(b)2., Florida Statutes, because it did not show by a preponderance of the evidence that [Ms. Cherry's] driver's license was suspended because she refused to submit to the breath-alcohol test after being requested to do so by the law enforcement officer. Based upon the court record, this Court concurs with [Ms. Cherry's] arguments IV and V and finds that the hearing officer's decision to sustain [Ms. Cherry's] license suspension departed from the essential requirements of the law and was not based on competent substantial evidence. Because [Ms. Cherry's] arguments IV and V are dispositive, the Court finds it unnecessary to address her other arguments.
316.1932(1)(f)3

The person tested may, at his or her own expense, have a physician, registered nurse, other personnel authorized by a hospital to draw blood, or duly licensed clinical laboratory director, supervisor, technologist, or technician, or other person of his or her own choosing administer an independent test in addition to the test administered at the direction of the law enforcement officer for the purpose of determining the amount of alcohol in the person’s blood or breath or the presence of chemical substances or controlled substances at the time alleged, as shown by chemical analysis of his or her blood or urine, or by chemical or physical test of his or her breath. 

The failure or inability to obtain an independent test by a person does not preclude the admissibility in evidence of the test taken at the direction of the law enforcement officer. The law enforcement officer shall not interfere with the person’s opportunity to obtain the independent test and shall provide the person with timely telephone access to secure the test, but the burden is on the person to arrange and secure the test at the person’s own expense.


Criminal Defendant Privilege Miranda Rights


In Miranda v. Arizona, 384 U.S. 436, 86 S. Ct. 1602, 16 L. Ed. 2d 694 (1966), the Supreme Court extended the right to remain silent to pretrial custodial interrogations. The Court held that before a suspect is questioned, the police must apprise the suspect of his or her right to remain silent and that if he or she gives up this right, any statements may be used against the suspect in a subsequent criminal prosecution. Under Miranda, suspects also have a Fifth Amendment right to consult an attorney before they submit to questioning. Miranda applies to any situation in which a person is both held in custody by the police, which means that he or she is not free to leave, and is being interrogated, which means he or she is being asked questions that are designed to elicit an incriminating response. A person need not be arrested or formally charged for Miranda to apply. For criminal defendants, the privilege against self-incrimination includes the right to refuse to testify at trial. A defendant may testify at a Preliminary Hearing on the admissibility of evidence without waiving the right to not testify at trial. Incriminating statements made by a defendant in a preliminary hearing are not admissible at trial, and the prosecutor may not comment on them.

The FDLE Purposely Covered Up the Fact the Breathalyzer Tests Were Not Functioning Properly

Now I no way condone drunk driving.  In fact, I am against drunk driving.  In fact, I have a friend his teenage boy was crashed into by a drunk driver.  Left paralyzed for the rest of his life.
 
My mission is to make sure citizens are being treated fairly and justly.   

Thousands and thousands of people have been arrested and was charged for refusing a breathalyzer test. 
 
In spite of how hard thousands of people blew into the Intoxilyzer  8000 serial number 80-001321 software 8100.27 the results was considered not reliable to determine breath alcohol level.

Which is a result considered a refusal.  Thousands and thousands of people may have not been drinking and driving at all or blew such a high alcohol level that will kill an elephant which is not humanly possible.

The fact remains the FDLE new the Intoxilyzer  8000 was not functioning properly but continued and kept arresting people with DUI with a refusal to blow charge.   

Knowing The Intoxilyer 8000 is not working properly and is not a reliable source for evidence.   

In fact as far back as 2007 its been covered up by the FDLE not even approved by the (Authorized for Use in the DOT & FMCSA Program)

Myths and Facts about Alcohol Consumption

Someone using a breathalyzer

Myth 1: "Alcohol on the breath" is a reliable sign of alcohol consumption and intoxication.

Fact: Alcohol is actually odorless.... it has no smell. What people perceive as alcohol on the breath is actually the odor of things commonly found in alcoholic beverages. The breath of a person who drinks a non-alcoholic beer will smell the same as that of a person who has consumed an alcoholic beer. 

Myth 2: People who abstain from alcohol are "alcohol-free" and can't be arrested for DWI. 

Fact: The human body produces its own supply of alcohol naturally on a continuous basis, 24 hours a day, seven days a week. It's called endogenous ethanol production. Therefore, we always have alcohol in our bodies and in some cases people produce enough to become legally intoxicated and arrested for DWI. 



‘Alcohol on the breath’ is not a reliable sign because alcohol is actually odorless. When people detect ‘alcohol on the breath,’ it’s actually the odor of things commonly found in alcoholic beverages. For instance, the breath of a person who drinks a non-alcoholic beer and a beer containing alcohol will smell the same.

In a study to test whether estimates of alcohol on the breath were reliable (Moscowitz, H., Burns, M. & Ferguson, S. Police officers’ detection of breath odors from alcohol ingestion, Accident Analysis and Prevention, 1999), experienced police officers were asked to detect an alcohol odor from 14 subjects. The subjects were at blood alcohol concentrations (BACs) ranging from zero to 0.13, and odor detection was over a 4 hour period, and before and after the subjects consumed food.

The result: Odor strength estimates were unrelated to BAC levels and estimates of BAC level failed to rise above random guesses. The researchers concluded that estimates of alcohol on the breath cannot be relied upon.



The “Lambert-Beer” law states that the amount of infrared light absorbed by your breath is proportional to the amount of alcohol in the sample. But the Intoxilyzer cannot account for all interferents that end up being in the sample and misread as alcohol.
3. If you take several deep breaths or hyperventilate before blowing into the Intoxilyzer, this can have the effect of cooling your lungs and resulting in a lower blood alcohol (BAC) reading.


Problems with the Breath Test Can Include:

In the video I had mentioned being sick and mentioned I had breathing problems several times.

I blew as hard and as long as I could with several attempts.
I could not blow for more than 6 to 7 seconds.  I was required to blow 10 seconds.

After several attemps to blow I asked why can’t I get a blood test since I am un able to blow?

During the session I mentioned speaking with an attorney in the evidence video. 


Here is What Can Be Used for My Defense

·  The defendant asks for an attorney before deciding whether to take the breath test;
·  The Defendant asks for an independent blood, breath or urine test;
·  The Intoxilyzer 8000 was not in substantial compliance for any of the following reasons;
  • The first two breath sample readings are not within .02 agreement;
  • The driver was told to blow into the machine until told to stop;
  • The first two samples did not occur within 15 minutes of each other;
  • The driver was wearing dentures which may have caused a high reading:
  • Some unauthorized person entered the breath testing room;
  • The law enforcement officer failed to follow the 20 minute observation rule;
  • The agency inspector used tap water instead of distilled water.
·         ·  Motion for Inspection giving the right to inspect the interior, electrical and computer components of the Intoxilyzer 8000, as well as the software and source code for the computer program used in the operation of the instrument and the instruments qualitative and quantitative analysis of and calculations of breath alcohol content to insure that it works in a scientific manner; and
·         ·  Motion to Suppress (Throw Out) the Breath Test Machine Because the Intoxilyer 8000 is not an "approved machine" under Florida law because the breath test was not actually approved since it was not in compliance with the FDLE Rules.

·         For example, by inspecting the records pertaining to the Intoxilyzer 8000, experts have now established yet another software flaw that allows the machine to produce a breath alcohol level when the machine reports that no breath volume was submitted for analysis.

·         One of the safeguards of the machine is the ability to record the volume of each breath. When that breath sample is less than 1.1 liters, the machine should report to the breath test operator the warning "volume not met." If that warning is not provided, then the machine should have calculated that the sample volume is greater than 1.1 liters. However, no methodology used by FDLE can verify the breath volume is accurate for any given breath sample.

·         For example, by inspecting the records pertaining to the Intoxilyzer 8000, experts have now established yet another software flaw that allows the machine to produce a breath alcohol level when the machine reports that no breath volume was submitted for analysis.

Facts and References to Expose Breathilizer Refusal



Fact: Alcohol is actually odorless.... it has no smell. What people perceive as alcohol on the breath is actually the odor of things commonly found in alcoholic beverages. The breath of a person who drinks a non-alcoholic beer will smell the same as that of a person who has consumed an alcoholic beer.

Research using experienced law enforcement officers has found that odor strength estimates are unrelated to blood alcohol concentration (BAC), which ranged in the experiment from zero to .13 (almost twice the legal limit for driving). The estimates made by the officers were no more accurate than random guesses. The researchers concluded that estimates of alcohol on the breath are unreliable.



Fact: The human body produces its own supply of alcohol naturally on a continuous basis, 24 hours a day, seven days a week. It’s called endogenous ethanol production. Therefore, we always have alcohol in our bodies and in some cases people produce enough to become legally intoxicated and arrested for DUI.

Fact: Hypoglycemia causes acetone in the breath, which the Breathalyzer will record as alcohol on the breath. Unfortunately, about one of seven drivers is diabetic and at risk of false arrest and conviction for DUI/DWI.

http://www2.potsdam.edu/alcohol/DrivingIssues/references/1107196613.html#4

Fact: A study conducted by scientists at Clemson University involved showing police officers videotapes of individuals taking six common field sobriety tests. The officers were asked to decide whether suspects were too intoxicated to drive legally. Unknown to the officers, none of the suspects had a BAC above .000. They had zero alcohol in their blood. However, in the professional opinion of the officers, 46% of the completely sober individuals were too drunk to drive! Therefore, use of field sobriety tests led to judgments by law enforcement officers that were about as accurate as flipping a coin.



Fact: There are many, many sources of error in breath testers. For an explanation of some of them visit Breath Analyzer Accuracy.

Smoke?

Here’s something to think about. Acetaldehyde is a compound in the breath that is falsely recorded as alcohol by breath analyzers.
Important for tobacco smokers is the fact that acetaldehyde levels in their lungs are much, much higher than those in the lungs of non-smokers. 10 This means than smokers are far more likely to have falsely high readings on a Breathalyzer or other machine.
The danger of arrest and false conviction of DWI/DUI is yet another reason to quit smoking.

Even in the absence of any of these common problems and under ideal conditions, alcohol breath testers simply lack precision. Law professor and attorney Lawrence Taylor explains that “Scientists universally recognize an inherent error in breath analysis, generally of plus or minus .01%.” In addition “This has been acknowledged by courts across the country (see, for example, People v. Campos, 138 Cal. Rptr. 366 (California); Haynes v. Department of Public Safety, 865 P.2d 753 (Alaska); State v. Boehmer, 613 P.2d 916

(Hawaii), recognizing an even larger .0165% inherent error). 6
This means that under ideal conditions, which is a highly unlikely situation, a BAC reading of .08 reflects an actual BAC of anywhere from .07 to .09 or even .065 to .095. That’s a margin of error of 20 to 30 percent.

Would this be considered a reasonable margin of error for an accountant, airline pilot, or bank teller? Is this a reasonable margin of error in court, where guilt should be proved beyond a reasonable doubt?

Fact: Law enforcement officers can and do influence BAC readings. Law professor and lawyer Lawrence Taylor quotes Dr. Michael Hlastala, Professor of Physiology, Biophysics and Medicine at the University of Washington

"By far, the most overlooked error in breath testing for alcohol is the pattern of breathing.... The concentration of alcohol changes considerably during the breath...The first part of the breath, after discarding the dead space, has an alcohol concentration much lower than the equivalent BAC. Whereas, the last part of the breath has an alcohol concentration that is much higher than the equivalent BAC. The last part of the breath can be over 50% above the alcohol level....Thus, a breath tester reading of 0.14% taken from the last part of the breath may indicate that the blood level is only 0.09%." 8
Professor Taylor explains that

“Many police officers know this. They also know that if the machine contradicts their judgment that the person they arrested is intoxicated, they won’t look good. So when they tell the arrestee to blow into the machine’s mouthpiece, they’ll yell at him, "Keep breathing! Breathe harder! Harder!" As Professor Hlastala has found, this ensures that the breath captured by the machine will be from the bottom of the lungs, near the alveolar sacs, which will be richest in alcohol. With the higher alcohol concentration, the machine will give a higher -- but inaccurate - - reading.”


One investigator has reported that alcohol-free subjects can generate BAC readings of about .05 after eating various types of bread products.
Substances in the environment can also lead to false BAC readings. For example, an alcohol-free subject was asked to apply a pint of contact cement to a piece of plywood and then to apply a gallon of oil-base paint to a wall. The total activity lasted about an hour. Twenty minutes later the subject was tested on an Intoxilyzer, which registered a BAC of .12 percent. This level is 50% higher than a BAC of .08, which constitutes legal intoxication in many states.

Ignition Interlocks

An ignition interlock is a device installed in a vehicle to prevent its use if a driver has been drinking alcohol. It includes a breath testing device into which the driver must blow before starting the engine.
The blood-alcohol concentration (BAC) limit for starting the car is very low, under .025, which is less than 1/3 the legal limit of .08. Therefore drivers are advised by authorities not to eat or smoke before trying to start their vehicles. Otherwise, the device may prevent them from driving.
Repeat DUI offenders to get ignition interlock: blood-alcohol level must be below .025 to start car. TheWGALChannel.com, 10-1-03.
 
Similarly, a painter with a protective mask spray painted a room for 20 minutes. Although a blood test showed no alcohol, an Intoxilyzer falsely reported his BAC as .075.
Any number of other products found in the environment can cause erroneous BAC results. These include compounds found in lacquers, paint removers, celluloid, gasoline, and cleaning fluids.

Other common things that can cause false BAC levels are alcohol, blood or vomit in the subject's mouth, electrical interference from cell phones and police radios, tobacco smoke, dirt, and moisture.

Breath testers can be very sensitive to temperature and will give false readings if not adjusted or recalibrated to account for ambient or surrounding air temperatures. The temperature of the subject is also very important. Each one degree of body temperature above normal will cause a substantial elevation (about 8%) in apparent BAC.

Many breath testing machines assume a 2,100-to-1 ratio in converting alcohol in the breath to estimates of alcohol in the blood. However, this ratio varies from 1,900 to 2,400 among people and also within a person over time. This variation will lead to false BAC readings.
Physical activity and hyperventilation can lower apparent BAC levels. One study found that the BAC readings of subjects decreased 11 to 14% after running up one flight of stairs and 22-25% after doing so twice. Another study found a 15% decrease in BAC readings after vigorous exercise or hyperventilation.

Some breath analysis machines assume a hematocrit (cell volume of blood) of 47%. However, hematocrit values range from 42 to 52% in men and from 37 to 47% in women. A person with a lower hematocrit will have a falsely high BAC reading.

Failure of law enforcement officers to use the devices properly or of administrators to have the machines properly maintained and re-calibrated as required are additional sources of error.

Research indicates that breath tests vary at least 15% from actual blood alcohol concentration. At least 23% (that's about one out of every four) of all individuals tested will have a BAC reading higher than their actual BAC.
One writer has observed that

Breath testing, as currently used, is a very inaccurate method for measuring BAC. Even if the breath testing instrument is working perfectly, physiological variables prevent early reasonable accuracy....Breath testing for alcohol using a single test instrument, should not be used for scientific, medical or legal purposes where accuracy is important.


Were you sick at the time of your DUI arrest?  The temperature of the subject is also important. For each one degree of body temperature above normal, a breath alcohol tester will cause an increase of approximately 8% in the estimated BAC reading.





Here is a video of a person making multiple breath sample attempts the argument was no one could prove which breath samples were valid without the source code also what samples was analyzed or which one was reported.
Other bracks cannot be reported that are taken from highest bracket.
The display of readings are supposed to be off in Florida so that the results cannot be manipulated.
