I am going to have to stick with the facts as I know them.
1) If the police thought they had a case aginst the guy, they would have charged him.
Yeah, maybe.
Information now out seems to point pretty clearly to a whitewash investigation.
Witnesses claim they had trouble getting the attention of the police department in order to give statements.
Witnesses who were interviewed by the police, claim that they were coached, or witnessed coaching by the police.
Witnesses claim that the police interviewers used leading questions, cut off testimony to "correct" answers and other investigation errors.
A witness who heard the cries for help, said the heard, but didn't see and thus couldn't be sure who of the two was screaming for help, but was pretty sure it was Trayvon. The police claimed he said it was Zimmerman.
The investigation was so obviously botched that the Chief of Police has stepped down.
This case should have been sent to the Grand Jury based on what we all know:
An unarmed person was shot dead.
At no time did the shooter have any reason to believe a crime was being committed by the victim.
The shooter followed and approached the victim.
Though the shooter claims self-defense, there are witnesses, physical evidence, phone records and recorded phone calls that all can be used to corroborate or discredit the shooters claims.
Thus, the police are required to perform an investigation, provide to the D.A., who should have sent to a Grand Jury for a possible indictment.
It is not for the police to decide. This scandal wouldn't be such a huge deal if a reasonable investigation had been performed, sent to a Grand Jury and they had decided not to indict.
