This is something you have to accept. Because the US population is extensively armed, law enforcement, including the federal agencies, will be better armed.
And you should also realize, that if certain events take place, and certain situations arise, the US Northern Command ascends to authority over the nation.
Most of the agencies are indeed what’s referred to as armed agencies. Intent meaning sidearm or long arm in certain instances. They were never intended to be para-military. And, no, I don’t have to accept it. But, you obviously have.
