I don't know what's going on here:
They're filming a movie at Knicks-Nets, so there's some possibility this was staged, but people I've spoken to at the arena believe it really happened, and I see no cameras, and people tweeted about it as it happened:
Guy got bounced @ the game for putting his prosthetic leg on his head and fighting with security and all Knicks fans... Brooklyn #knicks— Dylan Seymour (@dcubby01) December 3, 2014
They just carried a dude out who has one leg. He didn’t want to leave and they had to get security #Knicks— Kareem Ali (@RealKareemAli) December 3, 2014
MSG employees suggest he actually brandished the leg as a weapon:
MSG Employee just told me this dude hit someone with his prosthetic leg before he was ejected. NYPD was called http://t.co/ydNxALTe3T— Kenny Ducey (@KennyDucey) December 3, 2014
MSG staffer says that the Nets super fan that was kicked out without his prosthetic leg was ejected because he had hit somebody with it.— Nick Metallinos (@NickMetallinos) December 3, 2014
Witnesses say he didn't:
@KennyDucey I was a few rows behind him. No one near saw him swing his leg at anyone. He was just being loud.— +1 (@plusonemusic) December 3, 2014
@KennyDucey the whole section was chanting "let him stay" & security patiently talked to him for a few minutes before carrying him out.— +1 (@plusonemusic) December 3, 2014
And The Brooklyn Game has a story from a fan who says security escalated the situation:
After halftime a guard came up and told him to "cool down and just be a fan." Obviously didn't know who he was. He said what did I do wrong? Should I be quiet? They said no, just cool it down. He started loudly cheering FOR the Knicks doing "go New York go New York go," etc. The guards came back and told him to stop. He said why? Is this a library?
Then the main guard on the floor gave the signal to kick him out. He would not leave. A guard then touched his leg and he said "ouch you're hurting me I have a prosthetic leg." He then took off the leg, which is when things escalated.
More and more guards surrounded him as he watched the game with his leg resting on his shoulder. They tried to get him to put his leg on, threatened to arrest him if he wouldn't, but he wasn't moving.
He started saying "why are you doing this I just love basketball so much," he was clearly overwhelmed.
After about ten minutes, four guards grabbed him and carried him out as he screamed in pain.
And one more from the person who filmed the video above:
The fan in question is one of the Nets' most well-known fans, Jeffrey Gamblero:
