ANN ALTHOUSE CORRECTS AL SHARPTON AND JESSE JACKSON:

Zimmerman shot when he was pinned down and getting his head bashed into concrete. Stand-your-ground has to do with retreating when you can. Even aside from the fact laws can’t ensure that bad things never, ever happen again — or else why is there murder? — stand-your-ground made no difference in Zimmerman’s situation. . . .

We need something concrete.
.. Speaking of concrete, does anyone at these rallies mention that Martin bashed Zimmerman’s head on the concrete?

Of course not. Mentioning that would be racist.
