Yes, I clearly remember being a just turned 17 year old Marine with a not fully developed prefrontal cortex, and, at that time, I would have eagerly fixed a bayonet on my M1 Garand and assaulted the Gates of Hell. If anyone thinks a 17 year old can't be extremely dangerous, they're wrong.
You lady have a DEFORMED CRANIAL. Trayvon chose to stick around and confront Zimmerman. He did not know if this was a robber, cop or thug. That is how a STREET THUG OPERATES not a little boy. He made a huge mistake. Quit with the phony crocodile tears and turn your effort into the inner city black kids getting slaughtered each day.
I don't remember where I read it or who said it (Heinlein?), but I haven't found much to counter the quote "The single most dangerous animal on the planet is an adolescent human male."
