He doesn't have to be a thug to be wrong. I don't have enough information to call him that -- and I don't need to in order to be on Zimmerman's side. Hell, from what I've heard of Martin's background? I was one helluva lot worse than him in high school.
We all profile. We do it every day. We glance at someone and we make judgments. That skill helps keep us safe...when it's working right.
I'm waiting for an elevator. It stops at my floor and inside stand two guys with hoodies, tats, sunglasses and one carrying a black satchel of sorts. I'm not getting on that elevator. "Oops, forgot something," as I spin around and head in the other direction. I've done it. And it's profiling.
I'm in an enclosed parking garage walking to my car. I see a guy staggering around the garage, obviously drunk as far as I know, and decide to get an escort to my car. Profiling.
Before I flip somebody the bird in my rearview mirror, I'm going to profile the driver, too.
Nothing wrong with profiling by you, me or law enforcement. As long as you don't violate anyone's rights.
