Pretty circumstantial evidence at this point, someone who I can't recall (SpeedyGose maybe) may have correctly pointed out that half the issue is the fact that you can't have any alcohol in the system when under 21 anymore. Obviously drinking and driving is wrong, and if JV did it he should thank his lucky stars he didn't hurt anyone. With that being said, given the ambiguity of it all, he should be fine and this will be forgotten about if he never does this again.
