Forget sex offender register ...

I have to agree. Publicly accessible sex offender registers are lame and probably counter productive.

If we're serious about protecting our children from sexual abuse, then we need a strategy which deals with the facts.

Fact is most child sex offenders have not been caught yet so they are not on any register. Thinking you can sleep better at night because a sex offender register exists is unrealistic to put it mildly and politely.
