Something anti-American about suspending anyone until all the facts are known, so I wouldn't suspend anyone just yet. Arenas got suspended for his public displays especially that cowboys and indians act at a game, with his teammates laughing the whole time, that really must have ticked off Stern.
The latest that is being reported is that Arenas left the guns in Crittenten's locker with a note saying "pick one", like in a duel. It's also being reported that Crittenten had a gun of his own that he ****ed and started waving around the locker room. With the stories and information just hearsay at this point, I would just focus on getting the most accurate picture of what happened. I don't know if you can empanel a grand jury since no crime was committed but that would help in forming a true picture of what happened because the people that testify would be under oath.
