DUI Arrests, Hidden Lies

Ok, DUI Blog is an interesting stop. Head over and check out the sidebar titled "Library" for a topic that interests you. Just how far will our system go to insure a conviction. This topic is on Breathalzers.
"The results indicated that holding your breath for 30 seconds before exhaling increased the blood-alcohol concentration (BAC) by 15.7%. Hyperventilating for 20 seconds immediately before the analyses of breath, on the other hand, decreased the blood-alcohol level by 10.6%. Keeping the mouth closed for five minutes and using shallow nasal breathing resulted in increasing the BAC by 7.3%, and testing after a slow, 20-second exhalation increased levels by 2%."

This crap gets used as evidence??? And it appears police know it is crap
"Many police officers know this. They also know that if the machine contradicts their judgement 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."
I was thinking I would end by saying, "I don't drink so I have nothing to worry about". Reading this, anyone of us could have our lives "legally" ruined.
So what kinds of compounds may be on a person’s breath that can cause false BAC readings in a DUI case? In one study of eight men, 69 different compounds containing the methyl group were discovered.

And the Field Sobriety Tests are crap too.
