What a terrible, horrible story. This must be a terrible shock for the community which apparently has a low crime rate.

Things seem to have changed or at least the perception of the danger from murdering paedophiles (they always seem to have been around even before industrialisation), since I was a young child in the mid 1970s, where the main danger at the time was the wider spread introduction of motor cars running over children. I must have been about 7 when the Green Cross Code Man (who later went on to become Darth Vader and 2IC for the Empire) turned up at the local primary School to instruct us of the dangers. I still walked back to and from the school the mile or so on my own (from about 7 years old) or with some friends who lived nearby.
