Actually, it's not up to the FBI to “jail” anyone. It up to the Senate Judiciary Committee to make referrals for prosecution to the Just Us Department. Then, it's up to President Trump to see to it that they actually do their jobs and conduct the prosecutions. But you are right, the only way that these abuses stop is for people to be prosecuted, found guilty and jailed for significant periods of time. I mean look at this little RAT turd Cosko who leaked private information about Senators using House secure computers. We are told he's been arrested and is facing as much as 50 years behind bars for what he did. Right now, I'd be happy to see him go in for at least 10 years. I guess we will see, won't we?
Why does the judiciary have to refer death threats to senators and their families? Who protects congress? The DOJ should be on this.
