How is that unusual?
They have standing emergency contracts with FEMA and HS.

Why would they keep staff full time when needed only occasionally?

They are professional security people and I would wager that most whiners would be extremely grateful to be able to call on them if their kids or parents were taken by or in the way of a mob.

Your lies are not needed nor helpful. They are mercenaries, nothing more. Thugs, to boot. NO federal force used against the citizens of the US is constitutional.

Shut up.
