That's the point...charge him with criminal negligence or something like manslaughter and he gets rightly convicted of an appropriate charge.
Then there's no rioting, no years of race bickering, no ignorant outrage from people thinking a "not guilty" verdict means he didn't do anything wrong, etc., etc.
according to the talking heads on the news -
the prosecution has the abilty to lessen the charge, and probably will, to tell the jury "go ahead and make it manslaughter if you don't think we proved murder 2"
So manslaughter, serve 5 year of an 8 year bid, sounds like where he'll end up. It's probably the right charge. however, if the prosecution had the ability to change all along, it makes sense to aim high. I mean, you don't ASK your chick for a handjob haha. You ASK for sex, and then if it's not happening you SETTLE for the HJ or BJ. You don't just aim low or you end up handling things by yourself haha.
So if prosecution has had the ability all along to lower if it doesn't end well, it can scale back, and zimm will still go to jail.
