Hodges is being tossed out as a huge red herring but he'd be perfect. I can absolutely see him being a sociopath. Plus, it would explain why Wallace Langham didn't get added to the main credits and why he's had more screen time than half the main cast this season.

Also, last season CBS seemed to think we couldn't figure out that it was Brass who got shot so maybe they are stupid enough to think we can't figure out all the fingers pointing at Hodges.
