Did the Falcons management even think about this before announcing this stupid stunt? Maybe there is something to the brain damage allegations. The entire NFL seems stuck on stupid.
I have not been to an NFL game in years, but I would never go there now. It's going to be dangerous. NFL could have liability for the injuries that are going to be caused by all this stupidity.
Locking your arms with an unwilling person is an assault.
I think you have a right of self defense if some clown tries to lock his arms with you.
