Update on the Trayvon Martin killing:

CNN reports that George Zimmerman's attorney has now declared that the Florida stand your ground law doesn't figure in the case, and that his client will argue straight-up self-defense. The stand your ground law, the lawyer says, applies primarily to people being threatened in their homes, while Zimmerman, he claims, has a broader case for self-defense.

This seems a curious stance, since all the readings of the law I have seen, such as this one, clearly describe it as applying anywhere a person has a right to be, whether a public or private place. As such, stand your ground appears to offer Zimmerman's best chance at avoiding or beating prosecution. If a burly adult who actively chases a slender unarmed 17-year-old and then shoots him can't claim self-defense under the Swiss-cheese stand your ground law, how in the world is he going to make that claim under the traditionally more stringent standards of conventional self-defense?

It may be that Zimmerman's lawyer is retreating from the sheer public odiousness of a stand-your-ground defense, now that even the two Republican sponsors of the infamous Florida law are saying that the law doesn't protect Zimmerman and are calling for his arrest.

So, just as the law's authors are distancing themselves from him, perhaps Zimmerman's attorney is trying to distance his client from this now globally-detested law. Especially since Zimmerman is already a widely reviled figure, with public outrage spreading and unfavorable media coverage everywhere.

You could think of it as a lawyer in a rickety house hustling his client into the next room as the ceiling collapses.

At any rate, it looks like a desperate move by the attorney, and it may not be his last.

Not that there isn't a feasible chance that Zimmerman will get off, with or without a trial. But if he does, it may make the Rodney King riots look like a Sunday parade.

BTW, here is an interesting piece detailing a variety of cases in which Florida's stand your ground law has been used to fend off criminal charges for homicides in which the killers would otherwise likely have been indicted.

And here is a fact you personally need to know: although Florida was the first to enact a stand your ground law, similar laws have since been adopted by at least 25 states – that's half of America – including Alabama, Arizona, Mississippi, New Hampshire, Pennsylvania, South Carolina, and Texas. Think about that the next time some stranger pushes a confrontation with you.
