Guys who served in Afghanistan...particularly those who lost buddies there...most *assuredly* won't forget.
This pig would be wise to change his name after discharge.
No matter the name, he and his defenders/judge gotta sleep sometime.
Change his name and alter his appearance somehow. If he has any sense at all; he will crawl into a hole for a few years and let the general public forget about him; at least those who can.
Then surface with a new appearance and new name like you said. It’s his only chance at having a life but something tells me this guy will never work a regular job. He’s simply not mentally capable of anything more mentally strenuous than sweeping and mopping floors.
