Relying on the jury system Is silly. First of all, the DA only wants a jury trial if it helps him get reelected. Otherwise it clogs up the underfunded court system. If you get there you really will get slammed if you try for jury nullification explicitly which is pretty much what one of the GGP thought was what he could rely upon. I suppose he looks like a solid upstanding sort. Probably can afford a good lawyer.
oh well. I have read of a local case where a family was out camping and one of their nude kids ran through the camera frame. So they did get off eventually.
Moving on. If you do refuse the plea bargain then when you are in court everyone is already mad at you because you are not playing by the rules. Now you get convicted. Better be deeply remorseful even if you were completely innocent.
yet the above description may be the best system we are able to put together and defending it may prevent it from getting worse
