What was the proportion of kiddie fiddlers again ?
If I'm not mistaken, I seem to recall recently reading in these hallowed pages (this article) someone stating that kiddie porn was 0.2% of all cases, the proportion being relatively stable for the past decade.
Now, far be it from me to declare that the children being abused is negligeable, it is a horrible thing, but I don't see why I should give up my privacy for this.
Get the police to do their jobs and that will solve the problem.
