Test machines I find hard to trust as well after hearing over half of them were out of date/calibration or whatever. However I'm hardcore anti-alcohol (except for fuel usage ) and I can understand where the cop was coming from.

I wouldnt say he was overreacting in the least bit...if you drink 12oz and get in the car, regardless of tolerance/body weight, thats too much IMO. Wait an hour or whatever...I mean I understand some circumstances say otherwise, but just dont be so damn stupid and try to drown your sorrows in body altering chemicals

For the record, never had more than an ounce of alcohol in my body. Any possibility would be solely from the rare occasion of food marination, which is excellent ironically. Only beer/"adult beverage" I've ever had is O'Douls when I was like 8...so yeah
