Not trying to be "internet tough guy" because sometimes you can't say how you would act unless you there but man come on... I would like to believe I would have done something.
Not like he was getting butchered with a machete where this guy had a deadly weapon. Guy is strangling him with a rope.
If a chick is willing it get in there and hit the bad guy with some flowers, I don't think a swift kick to the head is asking too much of the rest of us.
SMH at the guy at the end just taking pics with his iphone. He can't even say he was running for safety. No he was just taking pics for the cops after the guy will be dead.
