In Florida, we are still trying to get over the deaths of 2 young girls, committed by previously convicted sex offenders. The courts decided that they were now safe to be placed into our neighborhoods. My T tells me that now research is telling us that these guys never get 'cured' of their warped desires. Evidently he is correct, because now the legislature in Florida is trying to pass tougher laws on the releasing of this scum into our communities.
The real problem lies in that once they are released, they move around without anyone knowing about it. There is not the manpower nor the resources for watching these perverts 24/7. Instead it has been up to the pervert to voluntarily register his new address each time he decides to move. Yeah, right!!!
I think what your neighbors did is awesome. We are doing that here in Florida, too, because the courts look after the welfare of the perverts, not the public. Plaster the freak's photo all over the place so everyone can watch out for him. The kids in your neighborhood especially need to know what he looks like, and know to be very afraid of him.
