This guy starts randomly singing some very loud songs and then at one point says to put a bullet in his head. The cops show up and escort him out. I don't know what this man is going through, but I hope he gets the help he deserves and needs. His body language and actions suggest he's got something going on that many people may not know about and he's trying to get it out of his system by acting out, maybe it's depression or a life event that took a turn for the worse. Wish the best for this man.
