Perhaps controversial but I think the FBI should have its policing powers taken away, and reverted back to a scientific agency that assists law enforcement, not investigate and make arrests of its own.
Somehow I don't think this country will have trouble finding folks to perform 'national-level policing'. From pop culture, I've gleaned that it's more often the opposite case: investigations are fragmented as a result of multiple organizations pursuing cases in their bureaucratic 'information silos.'
Ironic that one of the FBI's self-reported 'priorities' is to 'Protect civil rights.' I wonder how much longer Hanlon's razor will be a plausible excuse for this kind of lying...
I know about the other organizations, but are they any better in your eyes than the FBI? AFAIK, the DHS can be much more aggressive, perhaps lacking the Justice Dept's oversight.
