One thing people keep forgetting about criminal operations. You never give up the con, never. You go to your death denying everything, over and over. Never give up the con. You should write that down 100 times till it's a mantra in your mind. Confessions? Apologies? Forget about it. You have to hold the feet of these criminals to the fire for every grain of truth and they will go kicking and screaming to the gallows loudly claiming they are innocent even after you have them dead to rights on hard evidence.
