The MD Police fear the GUN not the person using it.
They live in a fantasy world where there are little to no guns on the street and every gun a law abiding citizen purchases becomes one gun they have to rid the streets of.
I think it's quite political. It's HARD to get guns from criminals. It's much easier to get them from law abiding citizens willing to obey the laws imposed upon them. You see all the gun violence, so the police take steps to make gun headlines. No, not actually rid the street of guns, just make headlines to make it look like they're doing something.
