@Brandon9000,
Those are good questions, but how about the right of a young teenager who goes to the store to buy candy and just walking back to his father's house?
He's followed by a wanna-be cop with a gun, and suspects he's up to no good, and follows him until they confront each other.
Martin didn't commit any crime, but his pursuer thought he was up to no good.
Thinking ill will is not illegal, but to follow somebody until they notice you and confronts you is a natural reaction - especially if your a black teenager who's done nothing wrong. Why are you following me?
Because I have a gun, and I wanna be a cop.
Well, maybe I should have stayed in my car, because the police were on their way. Yup!
