It all still sounds fishy to me.
One or two feral (spelling intentional) agencies with its own armed "enforcement" element is not too alarming. Ten years or so ago the Forest Service put their first "LE" units into the woods. Tongue clucking from the local citizenry ensued, not much else.
As things stand, I don't think there is an agency or department that does not have an armed element.
Our tenders have been dispersed throughout the fabric of "government."
By the way, one of the most boring jobs on earth has to be the guard at the local Soc Sec office. Except for directing the occasional customer to the sign-in kiosk, it is wait for lunch, then wait to lock the doors at night. Start over tomorrow.
But great pension and benefits. Perfect job for an EEO sluggard.
