The truth really doesn't matter anymore.
Like in the movie MINORITY REPORT, "everyone runs."
At this it no longer matters what is truth or what the evidence is, Zimmerman's only chase is to make a run for it. The police openly tried to set him up to be killed, blocking all address and contact information for witnesses, but Zimmerman's address and phone number released including then to the mob and to those making death threats. Media talking heads, politicians and now the spokesperson for the Justice Department - selecting an African-American woman - has declared Zimmerman guilty, that he engaged in a race-hate crime and in presenting why notably excluded even mentioning the ONLY eye witness says it was Zimmerman down on the ground with Martin over him - instead the Justice Department spokesperson declaring Zimmerman ran Martin down and shot him.
Zimmerman is a nobody, an average intelligence at best guy who got too deeply into opposing crime and mistakenly believing people should give a damn about others in their neighborhood. There is no good end for this out of Zimmerman. They can get him killed in jail awaiting trial, or beaten and raped in jail until he agrees to plea out. If he lives to make it to jail. He will get the crappiest possible appointed lawyer who really doesn't work for him, only the government.
Before there is a warrant for his arrest he should quickly make is plan, sell his truck fast if he can, gather all his pennies, and make a run for it. When you are a nobody and a major political party, every federal appointee whose job depends on the White House remaining Democrat and it to their advantage to crushing you as their political tool, the police are setting up for a lynch mob and those making death threats, and the political Justice Department openly distorting and hiding evidence for the goal of stirring up universal national hatred for you, you ain't got a chance.
Since there is no warrant as of yet for him I am aware of and the police already drove him out of his home, he should make a run for it because as of now its not illegal for him to do so.
