janeainsworth I felt uncomfortable about the parents' angry reactions, too. Replacing one potential violent outcome with another from a raging parent shook those children rigid. The balaclava'd people in the van could have had a lasting damaging effect, which is what education about meeting up with strangers is supposed to be trying to prevent. Children can learn in an effective way without being jumped on and bawled out.
In this country, there are some great drama companies going in to schools to educate children about the dangers of the internet. There are videos and lesson plans for discussing the isue, too. My DD includes this topic in her teaching with her group of 15/16 year olds at the academy school she works in, as do her colleagues. Hopefully, the message is spreading. Most children can envisage the danger of talking to strangers who ask for inappropriate photos and meetings.
Predatory sex offenders are not increasing, child abductions aren't on the rise - we just know more about those that do occur now and the method for attempting to entrap children changes with the times. We shouldn't get this out of proportion, though. Whilst we are educating children and a small number of vigilante-type groups are hunting down sex offenders like this, the sex offenders are gradually learning that they, too, could br risking their lives by going to meet a 'child' who could turn out to be a group of violent vigilantes.
