James Shaw Jr., 29, acknowledges that if he hadn't disarmed the gunman who murdered four people at a Waffle House in Nashville early Sunday, more people would have died, but he said in a news conference on Sunday that he isn't comfortable with the "hero" label. "On my Instagram and Facebook, everybody's calling me a hero, but I want people to know that I did that completely out of a selfish act, I was completely doing it just to save myself," Shaw said.
