Blow
to the breathalyzer
The Police Department's commonly used breath test, popularly known
as "breathalyzer test", to detect drunken drivers, produces
blown-up results - indicating a figure beyond the legally permissible
level - if the equipment is used improperly. A Sunday Times investigation
reveals that many police officers use it improperly, resulting in
unfair prosecution.
Drunk
driving is an offence punishable by a minimum fine of Rs. 2,000
or a minimum three-month jail term or both. In addition the driving
licence could be suspended for a year.
According
to experts, the officer should get the suspect to blow the breathalyzer
unit in one breath for 15 seconds, during which period the yellow
crystals in the tube turn green. If this colour change reaches the
red mark in the centre of the tube during the 15 seconds, it indicates
that the alcohol level in the blood has exceeded the legally permissible
level, which is 0.08 grams per 100 millilitres of blood.
However,
if the person blows the tube in more than one breath, the yellow
crystals will turn green and reach the red mark even if he has consumed
a small quantity -- even if the actual alcohol content in the blood
is below the required level.
Retired
police officers and Government Analyst Department sources confirmed
that blowing into the breathalyzer more than once could change the
outcome of the test.
A
Deputy Government Analyst said the suspect should be asked to blow
the breathalyzer only once and if he was asked to blow continuously,
the result would show a figure more than the actual level.
Our
investigation shows that many police officers order the suspect
to continue to blow more than once, waiting until yellow turns green
and reaches red.
This
is because the department cannot afford to use more than one unit
on one suspect due to financial strains, police offcers who did
not want to be quoted stated. The breathalyzer, which costs Rs.
1,500 in taxpayers' money, once used, cannot be used for the second
time.
Asking
the suspect to blow a second unit will cost the Police Department
another Rs. 1,500. Recently, a chef of a leading five-star hotel
was booked for drunk driving.
He
told the police officers who tested him that he, as the chef, was
only sampling a few spoonfuls of alcohol for culinary purposes,
"They asked me to blow the tube twice. I appeared in court
and pleaded guilty because I didn't want to go through the hassle
of a legal contest," he said. He was fined and his licence
was suspended for two months. Colombo Traffic Court lawyer Franklin
de Silva, told The Sunday Times many of his clients charged with
drunk-driving did not want to plead not guilty although they could
contest the charge on grounds that the test was flawed. "They
simply do not want to go through the tedious process of litigation,"
he said.
A
Sunday Times survey of a cross section of those who have been charged
with drunk driving reveals that they have been forced to blow the
tube more than once and in some instances as many as four times.
But City Police traffic chief R. M. Lafir defended the test, dismissing
the claim that the test produced warped results if a suspect was
asked to blow the tube more than once. He said a police officer
could get the suspect to blow the unit more than once until the
officer was satisfied with the test.
"The
breathalyzer test is the most accurate form of testing recommended
by the Government Analyst's Department," SSP Lafir said. He
said they detected as many as 60 cases on any day they conducted
breathalyzer tests. Usually, the Colombo City Traffic Police conduct
the tests on Friday and Saturday nights. From January to August
this year, police have detected 730 drunken drivers, using this
questionable test.
