Have you ever been attacked physically?

I was speaking with a good acquaintance about a week ago and he spoke how he was coming home on the subway when some young man stopped him on the platform to ask if he had change. He said he then felt a stinging then numbing pain on the left side of his face as his left eye started to close. His mouth filled with blood and three of his teeth were knocked from his jaw. He turned to see 5 other young men, one with a bat in his hand that he had just whacked him with. The young man looked stunned and tried to whack him again but he managed to grab the bat from him and proceeded to clear the platform of the young men by opening up a can of whoopass on them. He said all he remembered next was the cops pointing guns at him telling him to drop the bat and whatwas he was doing. He said he remembers telling the cop, “I am trying to kill these young men, but they won’t die”. They tried to charge him as the aggressor, but the fact in the end showed him to be the victim. Have you ever been viciously attacked be it part of a robbery or not?
