Sgt. Grey tells the squad that it’s a day to go after problem spots. Smitty isn’t thrilled and calls it playing whack-a-mole, so Grey assigns West to Smitty for the day.
Smitty plans to sit outside a burger joint and just watch the known convicts there until shift end but West decides to see how many are on parole and arrest them for congregating together.
One of the ex-cons, Gleason Dunn, runs off. West catches him and he’s holding bullets but no gun. Suspecting that Dunn dropped the gun when he ran, West finds a young boy playing with. The boy accidentally shoots his mom who later dies.
The DA lets Gleason go because his prints weren’t on the gun. Smitty encourages West to lie on his statement and say he saw Gleason with the gun but West won’t do that. Turn out the gun was used in an unsolved murder last year. It had DNA on it but there was no match in the system. Gleason’s DNA isn’t in the system.
West pulls in one of the other convicts from that afternoon and leans on him to give up Gleason, which he does. Gleason will now be charged with two murders but West still feels guilty that the boy’s mother died.
