Tom Morello At Occupy SF: Rage Against The Machine Rocker Rallies Crowd, Gives Away Tickets (VIDEO)

On Friday afternoon, rocker Tom Morello -- the Grammy Award-winning guitarist from Rage Against the Machine, Audioslave and the Nightwatchman -- visited Occupy San Francisco to show support and rally the crowd.

Before a crowd of about 100 people, Morello took the microphone and thanked the occupiers for "raising their voices" against the one percent of Americans who control over 40 percent of the nation's wealth. He then targeted Barack Obama for not prosecuting those who contributed to the recession and the economic disparity of the general public:

They have caused so much pain and economic disadvantage for so many people, it is a crime, and it's a crime that so far has gone unprosecuted. Now if our president, Barack Obama does not have the courage to close Guantanamo Bay, then I have this suggestion: that perhaps he opens those animal cages up and puts in some of those Wall Street criminals for what they've done.

The crowd cheered wildly along with Morello as he spoke. "I used to think I was alone," he said. "But I ain't alone anymore."

Twitter reports from earlier in the day rumored that Morello had planned to perform after his speech. "Now I'd originally planned to play for you all, but I've changed my mind," he said. "I have a better idea." Morello then handed out 100-150 free tickets to his show at Great American Music Hall on Friday night, much to the delight of the crowd.
