It looks like a fake, but when I first saw it the video was very disturbing, to me at least. It reminded me of a guy who put a shotgun under his chin and fired. It was on the side of the FDR Drive, (highway) in Manhattan, which is what most people consider NYC.
This poor man was in his 40's. He had beaten cancer a couple of times, then found out he had brain cancer. He was on foot, on the side of the FDR drive. I do not know why he picked that area, it was almost like he wanted to have people see it.
He blew away his lower jaw, most of his upper jaw and face. I had arrived on the scene shortly after he pulled the trigger. He was making guttural noises, since most of his jaw, mouth and face was blown away. He was on his hand and knees with his hands trying to feel for the shotgun. I grabbed the shot gun which was inches away from him. I called for an ambulance. He died two days later.
This was about 12 years ago. To this day I grieve for that poor soul and what he had to deal with. I will never erase that image from my mind. It kind of takes its toll on you to see so much suffering first hand.
