Carry the guns in the squad car.
I don't think they're saying keep the squad car guns in the safes. Just something extra available to give the staff a fighting chance in an emergency. I like the idea, though, I might suggest a pistol or two also.
I can’t imagine that any police department would ever give civilians access to department weapons on any circumstances let alone as a matter of policy.
For one thing their insurance or bonding agency would drop them like a hot rock.
