There is, in fact, a legal limit, and being pulled over below it can result in a DWI arrest, but only if the police officer suspects that you're "influenced." I can't imagine a police officer arresting someone because of mouth wash, or because they had a beer or 2 and were perfectly sober. When you go to court, for free, I might add, you can explain away any physical disabilities to the judge and they will not uphold the arrest.
Short of seeing evidence that police officers are compensated for arrests or that anyone has actually been convicted for a mouth wash or 1 beer offense, I'm just not buying it. We had a few people here in New Mexico that were convicted on under .08 BAC, but they were absolutely ****faced, each one of them, and there was no excuse for them to be driving.
One undeniable fact? Implied Consent. Fail to take the breathalyzer and you are arrested for DWI. Sorry, Mark, but I think thinks have changed since you were a police officer, because they can and very often DO uphold arrests and convict people for implied consent violations, and its a minimum suspension of a year, usually.
But Missa, I don't know what made you such an angry person regarding police officers keeping the streets clear of drunks, but whatever it was, I can't compete with that and appeal to your logical side until whatever causes it calms down.
