personally, i trust the word of an investigator who had all the facts...
over the choice of a police chief (an admin more than a detective, no doubt) who drives in on a sunday night to reverse course of the invetigator.
Then, he resigns over it. Really, it looks pretty shitty. You don't resign when you make a good call. You resign when you fck up.
It's akin to Issa being ready to charge obama with treason for that birth certificate... holder steps in and shuts down the investigation... and then Holder resigns.
Would anyone really say "Oh, obama must be innocent!"? lol
