Fuck that shit. Fuck it. The government screens for crazy, they're not going to let a known serial killer run around free like a bird. I would be seriously afraid of what he would be telling those people he's training. A lot. If he had critical information that no one else could teach them, then maybe he would be let out of his cell handcuffed and under guard for long enough to teach it to them. Maybe. The US government is not stupid enough to believe a known serial killer when he says "I pwomise I won't kill anyone else if you'll let me train your critical personnel!"

Also, I'm pretty sure that at the end of Obsidian Butterfly Edward was all for killing Olaf if he ever got near Anita again. Did he get hit on the head between then and now?
