IMO all federal employees who owe taxes should be terminated and their final paycheck, money due for accumulated vacation and retirement funds retained and applied to their taxes. If that doesn’t cover it, then freeze and confiscate their bank accounts and personal property. They should also not be eligible for any unemployment compensation or any government benefits.
I would IMAGINE that their tax returns are scrutinized with the proverbial fine tooth comb.
Also a tour of Alcatraz might bring ANYONE to his/her senses. Brrrrr.
