Breath Testing in DUI Cases
Intoxilyzer 5000. Long Beach Police Breath Machine
The breath test machine used in Long Beach is manufactured by CMI and
has been around for many years.  The breath testing process in Long
Beach is overseen by the Long Beach Police Department Crime Lab and
they have written the protocol for the administration of the breath test by all
officers.

Breath testing in general is susceptible to many problems, namely
contamination by mouth alcohol, interfering substance issues such as
acetone, failure to properly follow the regulations including the lack of a
continuous observation period prior to administration of the test.

The Intoxilyzer 5000 is notorious for giving false readings in a variety of
different circumstances.  For example, the machine often confuses the
substance acetone with alcohol.  Acetone is found in the mouths of many
people, particularly those with diabetes and blood sugar maladies.  In
addition, our attorney has successfully gotten the machine readings
suppressed in a number of cases that involve mouth alcohol and displays
an "Invalid Test" situation.  In at least two cases in the last year the lawyer,
Matthew Ruff,  has obtained an acquittal in criminal court and drivers
license suspension set asides in other cases where the Long Beach
Police and/or the CHP has hidden crucial evidence of breath testing
improprieties involving this machine.  In one noteworthy case the jury
disregarded a breath reading of a sample with .10% and found our client
not guilty due to the police officer improperly using the machine and then
trying to hide his mistakes.  In another case, the DMV in El Segundo threw
out a reading of a .13% when counsel proved that the machine may have
been reading mouth alcohol residue rather than true blood alcohol.  This
result was possible even though a Forensic Alcohol Supervisor from the
Long Beach Crime Lab testified that the machine was operating properly.

Modern day breath machines are touted as being reliable to determine a
DUI suspect's blood alcohol level.  Because the machines are used so
frequently they have taken on an aura of scientific reliability in the legal
system that has fostered an environment that sometimes overlooks
mistakes and "minor" deficiencies in the regulatory requirements.  It is the
job of the Defense Attorney to find these deficiencies and expose them in
order to keep the system form becoming rubber stamp for law
enforcement.
