If they understand the human brain to such a degree why couldn't they just erase the last 8 years (I think that's what he said) of his life and modify it explain why he's so rich and famous now?
Surely they have the ability to modify memories; I mean just the stuff in the first movie (the subway scene; the market scene) would require some real fast talking on the part of the authorities if memories couldn't be modified...
Did that make sense....
