I wish they could take this fear and use it to empathize with the fear black/trans/homosexual people feel on a daily basis. Then perhaps they'd be a little less judgmental about protests for these groups. Instead, all I ever hear from conservatives is excuses for white violence and condemnation of less violent protests by BLM/trans/homosexual people.
Releasing the warrant would expose Trump to the accusation on the warrant, for which Trump has not been convicted. It would treating Trump with less dignity than it treats other suspects. I find it incredibly ironic that you insist the FBI prove they are not anti-Trump by taking actions that would be anit-Trump.
By contrast, Trump could release the full contents of the warrant. He doesn't seem to want to. If it were just "overdue library books", why won't Trump release the warrant?
Just like any other search warrant. Trump is being treated like any other citizen.
I was a critic of the FBI during the Clinton, Bush, and Obama administrations. You are new to the field. The FBI has always been (and still is) a bastion of conservatism and a ruthless enforcer of the status quo. You're just now experiencing what liberal groups have been going through for decades.
