Frank is forced to lobby Reverend Potter's (from #206) support for the NYPD's gun buyback program, which follows one simple rule: bring your guns, no questions asked. However, when a gun linked to a robbery is brought in, Danny faces the dilemma over whether to arrest the suspect. He finally decides to bend the rules and coaxes the robber’s victim to make an ID of the man, only for it to turn out to be the wrong guy. When Frank learns of Danny’s actions, he is disappointed and urges him to start the case from scratch. Meanwhile, Nicky feels guilty for not sticking up for a friend at school and turns to Jamie for advice. Danny finally breaks the robber case when he uses his intuition to locate the actual suspect (who turns out to be the brother of the first man) and Danny is grateful to Frank for making him do things the right way.
