My point was that the prosecution doesn't have a case - all its witnesses are for the defendant, none are for the prosecution.
The state doesn't cause innocent people to submit to the ordeal of trial to prove or show their innocence. If Corey finds that all of the evidence augurs for Zimmerman, then that's what she should say and show to the public, without a trial as backdrop. If the evidence cuts for Zimmerman, that is why he not put on trial. The suspicion of guilt is not supportable with evidence.
If the alternative to the ordeal of trial is to simply live under a cloud of suspicion, I’d say you’re right.
But in this case, the alternative is to either get lynched or be forced to leave the country. The ordeal of trial is preferable, both to Mr. Zimmmerman and to society.
