If you make this happen somewhere in CT when I'm not traveling somewhere else, I'll be there.
Do you know any police officers who'd be willing to role-play the responding officer? If you have him/her outside the room and come in to question the participant and various witnesses you described and outline what would go in the report, that could be hugely eye opening.
You should give Jon Green at GOAL-Massachusetts a call. He and the late Darius Arbabi (a MA attorney) did a similar though not as extensive class called 'The Art of Concealed Carry'. (It also included some basic info on gun and holster options.)
