re: I have a feeling this officer is going to be railroaded.

I actually think that Obama and Holder are feeling the opposite pressure that a White President and Attorney General would feel. Remember, Bush 41's administration prosecuted and convicted the Rodney King cops for civil rights violations, while Holder didn't bring civil rights charges against George Zimmerman, despite the demands of "his people". Obama and Holder are keen to avoid the impression that they're trying to "stick it to a White cop", while a White administration would try to avoid the impression that they're insensitive to the suffering of Black folks.
