Whiskey® said:Therein lies the issue, regardless of your weight, you may be fine at 1.0 BAC and may show no signs what so ever of even looking at alcohol in the last 24 hours, while your buddy maybe lazy eyed and staggering at .08 BAC.
I don't know how you deal with that, though.
If you intentionally leave the laws written "gray," you get power-trippy cops like those described above deciding they don't like you and tossing you in jail for a 0.02%. I hate to think what those Texas cops would do to me when they see my Mass license!
You write the law strictly, i.e. "blow a 0.10% = DWI," you don't take into account a person's tolerance. Whatever that number is - if you've got a 110lb co-ed on her 21st birthday, she's could well be wasted at 0.08%. You want to let her off because she's little and has no tolerance?
I don't know how you get around this...
