I want to add something to what Mr. Freeman said. Prevention is very useful, but it doesn't replace deterrence. The two go hand in hand. Measures are needed to deter sexual predators from reoffending. In other words, we have to make life hard for them. At the same time, however, it is appropriate to educate children about certain things. For instance, if they are going to the convenience store, they should go with someone, not alone; that is very important. Those kinds of measures should be taken, but they should accompany and complement deterrents, not replace them. That is key.
