Protect your Children from Online predators

Hello Parents,
I was watching Tv, and i came across this show from NBC called “To Catch a predator with Chris Hansen” and realize that there are so many people out there (using the internet) that have some kind of mental problem. I mean this is serious stuff,these kind of people need help and parents need to protect their families at home. However children cant be supervised all the time, specially if they are becoming teenagers…
Do you agree with me?… Have you seen this show?…I think parents could find this software helpful…Here is the link.. and let me know what you think….
