Lady Gaga’s Bodyguards Act Fast [VIDEO]

Lady Gaga's got good reason to surround herself with bodyguards while on the road. After watching the video, you can clearly see the fan just wanted an autograph, but in the world we live in, you never know someones intent. He shouldn't of ran up on her like that, and I don't blame the bodyguards for reacting the way they did. Their job is to protect their client by any means necessary. I also don't think they used excessive force in any way.  Lady Gaga is on her "Born This Way Ball", with stops all around the globe.

What do you think? Were they justified in slamming the fan into the wall and then taking him to the ground?
