This is exactly the problem though - everything about the concept of "applying whatever charges that may stick" sounds predatory. Being thrown charges until something sticks is akin to being interrogated until something / anything damning is found against you - an inquisition. It's not shifting perceived risk, it's shifting real risk. If you're not charged for something, you're probably (right? correct me if I'm wrong?) not going to get convicted for it. If you /are/ charged for something, there's a chance you're going to get convicted for it. Terrible things don't mostly happen because people are monsters, they happen because people are apathetic to others' problems and value their own convenience and gain above all else.
