So amidst all the vitriol and wingnutski KGB rants, I don't see too much retro-analysis, of SPD dispatch instruction, to Watch-Captain Zimmerman: "We don't need you to do that."
It seems George is not what the dispatcher was prepared to wrangle, since he went out of his car, with his gun, looking to use it, which he did, killing Martin with a single shot, rather than wound or warn Martin. When Captain George went out of his car, the dispatcher had to take action, right then, no matter what other calls were going on, to say something.
That the dispatcher had to say anything at all under the circumstances is significant; George was a loose cannon, but instead of getting back in his car, to drive to meet police, he went after Martin, on foot, to approach him. Zimmerman intended to use the gun, however he could, he shot to kill, and that is murder-2.
The Feds are watching THAT, the NSA watches THIS FORUM and all like it, and you can use your own judgment, as to what a hate crime actually is, but I can see, how those get going, from reading all the circular-logic with vitriol, from wingnuts, which is supposed to get Zimmerman off, somehow. The Feds watch, and wait, for now. Let's see what happens.
As for the NSA, we don't need THEM to do us, but hey. They have a new house going up, in Bluffdale, Utah, capable of housing terabytes, plus. They are THE Bad Co., four times bigger, than the CIA. They can hook up with corporations, or other agencies, whatever they want. Unlike Zimmerman, they do crime, and never mind the time. I wonder what Feds make of all this.
