Yes, and accusations are a dime a dozen, battery can be anything from a brutal clubbing to throwing a wad of paper with ill intent, and resisting arrest is one officer's bad day away from being on your docket as well, should you be close to an unfortunate occurance. Context is everything.
And CONTEXT is what has been left out of the media screed you just quoted, which on the night of the killing included critical context in the NBC playback of the 911 call. You've been indoctrinated by a media machine digging up as much shit as possible on Zimmerman to try to get people to overlook the fact that they cut up the 911 call, deliberately, and with intent to race bait and perhaps start a race riot, friend AC. I call bullshit on the media. I call BS on unenlightened self-interest and circling the wagons to protect one's own. The media are one's that caused the prosecutors to overreach, because of public demand for it, and caused a failure to convict Zimmerman of the crimes he actually committed that night, and thus the real failure of justice. Overreach and hype. We need fewer people who believe the hype-machine's bullshit, not more. Doubling down on crap is not the solution.
That woman was crazy, and deserved 20 years, and the context shows it. What did the context in the Zimmerman case show? That he didn't commit murder. That is all.
