Steelers running back Rashard Mendenhall is being criticized for Twitter posts that question celebrations of the death of Osama bin Laden. "What kind of person celebrates death? It's amazing how people can HATE a man they have never even heard speak. We've only heard one side ...," Mendenhall wrote in a post on Monday afternoon. "I believe in God. I believe we're ALL his children. And I believe HE is the ONE and ONLY judge." When another Twitter poster suggested that bin Laden wasn't responsible for the Sept. 11, 2001, terrorist attacks, Mendenhall responded: "We'll never know what really happened. I just have a hard time believing a plane could take a skyscraper down demolition style." Mendenhall has 14,240 followers on Twitter, a number that increased last night after word of his bin Laden comments spread. The Steelers declined comment and Mendenhall couldn't be reached, but other Twitter members were quick to bash the 23-year-old running back.
