Why is Ben Roethlisberger suspended?

Because he's been suspended by the NFL for the first six games of 2010 and, as shown by Sports Illustrated's "The Hangover: Roethlisberger" piece, has a lengthy history of bullying almost anyone he comes in contact with to the point where he's committed sexual assault, forced the firing of a waiter he got angry with, and other loutish and bullying behavior.
