Remember, though, that the threshold for sex offender registration is fairly low (eg, statutory rape--18yo having sex with a 16yo...I think this counts?). I think the website may give at least some details on the crime, however. Also remember that the VAST majority of sex offenders know their victims. Your physical proximity to a sex offender truly may not matter in the slightest if that person has never met your child.

The other thing is...we never hesitate to put our kids in the car and drive them somewhere, right? I have never known ANYone who restricted car travel due to fear of car accidents. But statistically, if we really wanted to keep our kids safe, we would limit car travel with them as much as possible. Car accidents are the #1 cause of accidental death and injury of children and teens.
