Alcohol affects each one of us differently and at different rates and in different amounts. There are no hard and fast rules with which to detrmine how any one person might be impaired at .12, .08 or .02.
I agree alcohol does indeed hit people differently, but a person battling with alcohol for many years, as he claims to be, is not out of THAT out of control at .12...That I refuse to believe.
For his weight/size .12 is probably 6 beers in a two hour time frame...
True. During my youthful days, I could swig down a bunch of Vodka + Grapefruits in an hour, hit that level, and you would barely be able to tell I was drinking.
