S5·E13 Trick or Treat

It's Halloween, and before Dog and Beth can help the kids carve their pumpkins, they have some business to attend to. It involves knocking on doors and meeting the neighbors but instead of hunting for treats they're on the search for a fugitive. Their quarry is Robert, a tattoo artist with a bad habit of missing his court dates. Dog's first stop is the fugitive's house where they make an alarming discovery; Robert appears to collects weapon, lots of them. After questioning the neighbors Dog heads off to Robert's tattoo parlor. Does the fugitive's fondness for stockpiling weapons in his home extend to his place of work?
