Have you ever given a thought to what General Flynn would do in a prison setting? He would have the inmates organized in a NY minute. He would terrify the corrupt guards and staff, he would fucking OWN the warden.
Gangs? Organized criminals? They're used to being organized and who has proven to be the best organizers in the history of the world? General Officers. He would have that place humming like a beehive with him as the King Bee.
I bet that there are a lot of people breathing a sigh of relief right now who were dreading the most famous General in the news coming to their lockup.
