It will be interesting to see if anyone can correctly guess where Jim will go with this character.
Based on Bradley's report of his dereliction of duty, he'll be encouraged to take early retirement ... then get hired as private security for Larry Fowler, to persecute Harry full time for twice what he was making as police.
Seriously though, he's going to have a hard time trying to charge Harry for trying to kill him without a) touching on the motive and b) explaining why he has crush injuries instead of marks of a beating with fists. But he'll also probably succeed at sweeping shooting Karrin under the rug. I don't doubt Butters will try to do the right thing and accuse him, but with a record of being institutionalized and zero physical evidence, that's going to fall flat. He and Sanya were way naive about thinking the system would deal properly with Rudy.
So he'll probably continue trying to harass Harry ... but as I said on another thread, if he gets sufficiently in the way of Lara's plans for Harry, or starts getting nosy about her as an associate of Harry's, his psychology would make him a juicy target for any Skavis or Malvora she were to point at him.
