First of all, breathe ... Then modify your post so you aren't giving away names and locations that can identify you or others in a public forum ... There is a right way and a wrong way to go about this.

Call local authorities and ask them if they have the pedophile registered on the sex offenders list and if they have they notified families with children in your neighborhood that a pedophile is living in the area.

Ask them if fliers about the guy's history are available, and if it's okay to print them up and pass them out to the people you know who have children, or to post them up around the area.

Of course, you can also let the neighbors know what's going on and let it get around by word of mouth.

Whatever you do ... DO NOT CONFRONT the pedophile or do anything that could get you into trouble. this would make the pedophile very happy.

Again, breathe ... And do nothing until your anger has subsided ... Again, there's a right way and a wrong way to handle this.

Sincerely,
Pfrog
