The GOP House and Senate should create a contract with America and item 1 on the list should be to disarm all domestic government agencies except for: FBI, parts of Justice Department, and a small part of Treasury. I can’t think of any other agency that needs to be armed.
Forestry. But I would recommend 12 gauge slug or 45/70 for bear protection.
USPO, not a federal agency, but they have an internal policing organization to protect the mail from their own employees, I believe they are armed.
You make the assumption that the GOP is any less statist than the DNC? Silly me, who would that these days?
And have them give up the Capitol Police force? Good luck on that one.
And any weapons and ammo removed from the other departments are to be sold in the private market.
