This whole thing is simply making the defenses case, that z was assaulted.
They can attempt to minimize or discredit his injuries all the care to....Fact is he was physically assaulted and stopped the assault so his injuries would not be more severe.
After seeing the Prosecution playing the Hannity interview, I think I have this figured out.
The prosecution has known all along that the original inditement was bogus and they would never convict.
So the goal is to appease a certain segment of our culture with a trial and at the same time publicize and show how very clearly innocent Zimmerman is, even to the simple minded, all to avoid an excuse for riots and looting.
