The government, the BBC and Daily Mail have decided that they critical fact about the murderer Peter Chapman is that he met his victim on Facebook. Indeed according to Home Secretary Alan Johnson the British and American governments are thinking of "ways to flag up when a convicted sex offender goes online", because computers can be made to detect Paedo-fingers when they start tapping at a keyboard.
The focus on the least important aspect of the story, Facebook, is particularly absurd given that Chapman's crimes, including abductions and rapes of women, began well before the internet era. If he was prevented from meeting potential victims on the internet he could just as easily have gone back to the manner in which he found them before the internet. The danger wasn't that he was allowed online but that he was allowed out of prison.
On the plus side perhaps the hysteria about the internet will at least result in parents forcing their children out of the house, thus doing wonders for the child obesity rate.
