Maybe. In the US Virgin Islands that's what the governor has authorized the guard to do in order to make sure the guard has an adequate supply of guns and ammo to keep order through the upcoming hurricane.
I'm having a hard time seeing this as any sort of necessity at all. The guard is equipped with the usual armament in 9mm, .223, and 12ga and shouldn't lack for any of this. The guard is also limited to some fixed and modest number of people, all of whom live in the soon-to-be-affected areas.
Somehow I'm seeing this as creating a safe working environment for the looters.
