Trusting Criminals WHY????

I believe that criminals shouldn't be released into society because no one will be safe, and the government is putting everyone lives in danger. It's like they were already in jail for murdering, raping or stealing. Why release them even when they have good behavior they are really smart and can con people into thinking one thing and its different. You won't really know what they are thinking and no one really cares enough to  allow them to have counseling to find out. The government is wrong for releasing them, and it's in the best interest of whom if they are out. They should be put back unto jail they aren't in there for no reason some things they did they can't take back. If a murder killed someone I'm sure they was loved by someone in they caused pain, they can't give someone back there life. One of the men that was in jail as already left the country and they can't be trusted.
