You seem to be in belief of a police state that never does anything wrong.
The fact is this policy sets people up for confrontation. They are not told that if they refuse the breathalyzer they’re taking blood. If you give people an ‘either / or’ situation - which is exactly what it is - instead of HIDING that fact, just tell ‘em. Most people would rather take the breathalyzer.
This country is going totalitarian and police are being taught not to look at people as innocent before guilty, but everyone is guilty and it’s only a matter of time before we collect enough evidence against you before we get you. We’re passing more and more nanny laws that are turning regular people into law breakers for doing non-criminal things (not wearing a seat belt, for example).
The last thing this country needs is a DNA database full of innocent people. Having to give up samples on arrest (whether or not you are guilty) is just not right. It’s like UK’s orwellian progress. The police wind up being more interested in taking assets and property rather than taking down real criminals. They just become an extension of the collection arm of government.
Well... they'd be wrong if they did. NEVER, EVER take a breathalyzer... ever. DEMAND a blood test. At least, you have a chance of it being accurate.
