—Anyone with any sense would have let Zimmerman know what he was about.....if he had a right to be where he was.—
You and I would have, but a young man with “the chip” and the hubris apparent in his internet persona would have done what it appears Martin did.
Then again, you did say “anyone with any sense”. And that may be the problem here. Especially if he was under the influence of drugs.
Obviously, Zimmerman “dissed” Martin by suspecting him of ill intent,
so Zimmerman deserved at least a beat down, if not a beating to death.
(See, I can be “culturally sensitive”!)
