San Diego DUI Breath Test Defenses
- Failure of San Diego California
DUI police to do continuous observation of breath test
subject for entire 15 minutes before first breath sample.
San Diego Drunk Driving police allows cessation or interruption
in continuity of fifteen minute observation of person
tested prior to initial blow sample.
a) San Diego area police officer often improperly attempts
to include transportation time as part of required 15
minute observation period. San Diego area breath test
given within a few minutes of arrival at breath test location.
b) Officer required by law to remain in presence of subject
and be able to use all of his/her senses (sight, sound
and smell) to properly and logically conduct a true observation
during the 15 minutes before test.
c) Observation means a realistic ability to perceive by
actually paying attention to subject during the continuous
15 minute period.
d) San Diego DUI officer who purports to observe while
driving fails to tilt mirror in order to be able to see
subject in backseat or who fails to stay with subject.
e) San Diego patrol car has dispatch radio on, emitting
noises and interfering with officer’s ability to
hear what subject is doing while in the moving vehicle.
f) San Diego DUI officer goes to the trunk upon arrival
at breath test location often to put gun away, or walks
around before removing subject from police car, or leaves
subject alone at anytime during the 15 minutes before
blowing - e.g. use of restroom or telephone, or placed
in holding cell or area outside presence of cop.
- At some point during the important 15 minutes before
the San Diego DUI breath test, you have a slight burp,
belch or regurgitation of gas that is relatively quiet.
- Vomiting, burping, belching or regurgitation of gas
within 15 minutes of test, and with no rinsing of mouth,
or inadequate deprivation period before retest.
- You may not be a proper subject for breath testing.
You have a physical problem or health limitation:
a. gastric reflux, hiatal hernia or intestinal problem
(e.g. Gastro Esophageal Reflux Disease, Irritated Bowel
Syndrome, or Acid Reflux Syndrome) diagnosed and treated
before date of arrest;
b. dental condition (e.g. gum disease/gingivitis/pockets
around roots, dentures or bridgework which may trap mouth
alcohol and contaminate a breath machine sample);
or
c. respiratory problem (e.g. asthma, bronchitis, emphysema
or chronic obstructive pulmonary disease).
- Your behavior or actions do not make sense when compared
to San Diego DUI breath test results (perhaps also proven
by independent witnesses).
- San Diego DUI breath test room or circuitry has a problem
(e.g. Radio Frequency Interference from a cell phone,
officer's radio, copy machine or other equipment with
surge capabilities) which may cause machine to give artificially
high reading; smoking in or near machine; shared power
supply with heater or other appliance - must be dedicated
"clean" electrical source; or recently painted
walls or trim).
- You have had recent environmental exposure to volatile
fumes (lacquer, gasoline, paint, dry cleaning fluids or
even 409) which have cumulative reading, causing chemical
interference/falsely elevated result.
- Air bag defenses - "the Tyndall effect" -
diffusion of light; propellant exposure; cut lips; lung
and airway irritation & fluid build-up from caustic
gas propellant.
- (If available - unlikely in San Diego:) Video tape refutes
the high reading, supports sobriety.
- High test result, yet you never urinate for 3 to 4
hours or more - physiological impossibility.
- No intent alcohol (e.g. from Nyquil, Vicks Formula
44, lip balms, toothache drops).
- Food/mint/candy in mouth containing alcohol (e.g. Breath
Drops with SD alcohol).
- Interfering or contaminating substance from something
in mouth (e.g. Skoal snuff - wintergreen; Altoids curiously
strong mints).
- Not-in-agreement tests, without follow-up tests to
correct [both results must be within 0.02% of each other].
- San Diego DUI Officer refuses to permit your request
for a second, independent test. Denial of blood test -
the more reliable target with the more accurate method
of analysis.
- San Diego DUI Officer not trained or marginally trained
in accordance with the standards of Title 17 of the California
Code of Regulations (e.g. not trained in “theory
of operation” of machine).
- San Diego Drunk Driving Officer fails to follow manual
or training protocol.
- Inadequate inspections by machine inspectors (e.g.
no linearity proven).
- San Diego county DUI police report supports sobriety,
or lack of investigation of alternative causes.
- Blood alcohol level is “rising” - level
at time of driving lower than time of testing.
- Breath temperature elevated (e.g. caused by fever,
hot tub, sauna, detention in hot sun or back of patrol
car in summer, dancing, menstrual cycle, etc.)
- Breath to blood ratio (averaged at 2100:1) not proven
to be your ratio; show how minor error gets multiplied
2100 times; 0.12 = 17/10,000,000th of an ounce. Show you
have abnormally low blood/breath conversion ratio through
testing and toxicologist.
- Inherent sampling variability or margin of error (e.g.,
0.088 reading - state acknowledges +/- 0.01% precision
problem).
- Blowing pattern irregularity (e.g. blubbering and crying
causing artificially high water vapor problem).
- Strict high protein diet and then introduce carbohydrates,
thereby triggering auto-generated alcohol production when
ketones are converted to isopropyl alcohol (or the "auto-brewery"
syndrome).
- Diabetes, or are borderline diabetic or are hypoglycemic
and consume alcohol in any amount, causing conversion
of high acetone levels into isopropyl alcohol.
- San Diego DUI breath machine operator gets first BAC
results, which will not support a .08% per se case, then
waits a few more minutes and retests, obtaining a reading
above the per se limit.
- San Diego Drunk Driving Officer gives chemical test
admonition, but then goes too far by threatening dire
warnings for which there is no factual basis or misstates
consequences regarding possible license suspension.
- San Diego DUI Prosecutor fails to prove that results
were obtained within the 3 hour statutorily imposed time
(3 hours after driving ended) in order to invoke rebuttable
presumption that your BAC was at or over the limit at
time of driving.
- Alcohol was consumed during driving, after driving ended
or before San Diego DUI police arrived.
- San Diego DUI Officer gets fired, indicted, retires,
moves away, or dies.
- San Diego Drunk Driving Officer commits crime (e.g.,
obstruction of justice or perjury) in an effort to conceal
evidence; state cannot proceed, or more often makes an
illegal, warrantless stop or arrests you without probable
cause.
