I'll ignore your gratuitous insult at the end of your post.
It wasn't an insult, it was an opinion. I suggest you go to DK or DU, and you'll find the exact same rationale for the DoJ wanting their own autopsy.
The fact is, the Ferguson officials have shown that it's perfectly natural to second-guess them.
Police should always be second-guessed. Second-guessing isn't convicting them without due process, though.
The chief hold a press conference and states that Wilson was never aware of the pilfering of the cigars by Brown, then, an hour later, is on Hannity's radio show saying that he was.
This is the most pathetic bunch of police work I've ever seen. If Brown's eyewitnesses should not be believed, neither should Wilson's.
Great, if there are no credible witnesses, then there can be no charges filed. Case closed.
I will be sure to remember that you trust Holder's DoJ over a county coroner, though.
