Dead to Rights Cheats
Harder Boiled Mode
Hold L1 + L2 + R1 + R2 and press Triangle, Square, Left(2), Circle at the main menu. The difficulty in this mode is incredibly high especially when used with the Super Cop difficulty setting.
When you are locked up "Iron Point" and are walking around in the hall only two or three people will be around. One of them will run up to you and say something. As you run away, they'll start to walk away and then you can get in back of them and do the grab. They move so much that you'll eventually end up just breaking their back.
