Basically, in my story, I want my vigilante to have two encounters with the police. One happens when my superhero intervenes in the mugging, but is stabbed. I'm thinking of making the detective give him some sort of warning or something, but not arrest him. The second incident, the vigilante confronts a robber inside of a warehouse, and tries to wrestle a gun away from the bad guy. The gun goes off in the struggle, and hits his partner. All 3 are surrounded by cops and caught. This story takes place in Boston. What kind of jail time is he looking at? Can't imagine it would be anything crazy, but I'd assume either jail time or something else.
