For the most part, lawbreakers don’t appear to use very good guns. Lots of Jennings in those lots.

We really do not know how the PD and Sheriff acquired these guns. A lot of people simply turn in guns from estates into police.
A fair number of men are accused of Domestic Violence, and give up their guns.
Some may have been from game violations.
Over half are inexpensive guns, but over a third are of decent quality. Even Hi-Points can kill a big bear.
