You are completely correct. I'd also add that even if we assume everyone IS dangerous, would you really want to lock them away for 5, 10, 15 years without any thought as to what sort of human they'd be after that? My personal opinion is that we should treat these people humanely and with sympathy, but if GP is taking an extreme self-centered approach then why not consider the possibility that the system is creating people who are more dangerous to them in the long run?
