Steeler Running Back Has Lots of Intelligent Bones

His brain, not so much:

As spontaneous celebrations broke out in the hours after the nation learned bin Laden was shot dead by U.S. forces in Pakistan, Mendenhall used the social media site to denounce the response.

"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 message posted to the social media site on Monday.

Some Twitter users responded by asking if Mendenhall would have said "the same thing when people celebrated Hitler's death," others said it was "ignorant" to give bin Laden the benefit of the doubt.

Mendenhall posted a series of about six Tweets, including one questioning whether the collapse of New York's Twin Towers was actually the result of al Qaeda hijackers flying planes into the buildings.

"We'll never know what really happened. I just have a hard time believing a plane could take a skyscraper down demolition-style," said Mendenhall of the tragedy on September 11, 2001 that claimed 2,752 lives in New York City.
