It was, at the least, an overreaction and unprofessional.
Sort of to be expected, tho, when a job is so difficult and unpleasant, that it becomes hard to find anyone willing to do it. The hiring standards sink and the employees feel like they work in a war zone and are constantly on edge. Sort of like being a cop in Baltimore. Or working for the fire department in Hamburg.
Working for ICE is now probably more dangerous than joining the Marines.
