Oh you mean because the FBI would never flat out lie to get a subpoena or warrant that they could then go around using as a fishing expedition to see if they could dig up dirt on their political enemies and then when they find nothing else on them despite doing their best to dig up anything and everything, decide to go and falsify statement documents and then charge them with "lying to the FBI" and try their best to prosecute them as hard as they can, going even so far as to bribe and threaten the defendants lawyers, to get in on the fix....
OH wait, that is EXACTLY what the FBI just did recently, and thanks to our corrupt court system of fellow travelers, totally got away with even when it was exposed...
At this point, any small amount of good the FBI might accidentally happen to do, is vastly overshadowed by the brazen, in your face corruption, full on politicizing of the law and out right lies and deception as well as staging of events or purposely avoiding stopping tragic events for political gain, that they are constantly involved in.
The FBI might as well just admit they are nothing but the SS jackboots of the Democrat party.
I'm sure some SS types probably did help eliminate some rapists and murderers and child molesters, when they weren't busy rounding up Jews and other undesirables. Same thing with Stalin and Mao's Kommissars, sure they got rid of a few bad people while murdering millions of citizens.
Do we give them kudos for that or do we just say, you were evil, Tough. You don't get sympathy for saying "well I was in the SS but I was one of the ones trying to do good"...
