No. We cant. George's MapQuest skills, along with most of the other issues you seem to require are all pretty much irrelevant as far as I can see. You seem to have some personal threshold that needs to be met. George isn't smart enough....His fathers position too lowly for him to have gleaned adequate experience, not enough juicy details.....on and on.
Maybe whatever evidence allowed at trial will suffice for you, maybe not. But good luck to you.
I don't know if he is guilty or not. There just isn't enough publicly available evidence to support a guilty verdict. We have to have more than feelings, or speculation to arrive at a guilty verdict.
I do know that the racist pimps are making in almost impossible for George to get a fair trial.
With what we know now, I think it is more likely than not that Trayvon threw the first punch and was on the verge of killing George, but that's just speculation on my part. As the trial unfolds, we will know more, but will we ever know enough to convict George beyond a reasonable doubt? It doesn't seem likely at this point unless there is some more actual evidence that we don't know about at this time.
