It must be accompanied by other measures. Earlier, I mentioned bracelets. From what I know about how an offender is monitored every two weeks, there isn't much to it. The person just signs a log, and that's it. There are no safety measures and no real follow-up. When a sexual predator strikes, in the first few days, they are still feeling the rush of adrenaline. There may be a way to obtain information at that point because they still have a sensitivity. But, two weeks later, they have accepted their crime, they have come to terms with it. They can be in a situation and remain calm. If the probation officer questions them about their recent comings and goings when the crime happened two weeks ago, it does absolutely no good.
