Arrested for disobeying police in Florida. The situation and arrest alone is enough to show his character and decision making, which was revealed. This was four years ago and Arenas has not changed since, which has been proven,
Brought guns into a locker room (a place of employment, and a public place). We all know the story and the illegal actions and poor judgement that he had.
While having a chance to hold back and utilize common sense during the ensuing investigation, he continued his antics by "shooting" his teammates.
He faked an injury, lied to his coaches, then told the media before even telling the coaches. Um, if I lied to my bosses' face and then proceeding to get on our intercom and broadcast what I lied about...well, it's not hard to figure out.
