It has nothing to do with him being legally drunk. Its the fact that he's coming off a year long suspension which is due to being involved with the law 7 times. He had to be squeaky clean given his situation, and he did not do it.
Do you think they're going to admit to getting in a fight, which is pretty much asking for a suspension?
The fact that in Goddells guidlines that he gave Pac when he reinstated him, he said he has to keep his name out of the headlines. Pac failed miserably.
If this were any other player, and they got suspended, you better believe it would be blown out or proportion. But when you're a player who just gets reinstated after a year long suspension, and this happens to you, you deserve whatever you get coming to you, because you obviously are not very smart at obeying rules.
