I don't think there is an increasing rate of sex offences. I think there is merely an increase in the number of offences they are calling sex crimes.
I also think the whole sex crime registery should be stopped. It protects no one. Stigmatizes people, who have served the punishment for there crime, indefinitely. (wether or not reform was achieved, when possible) and lets face it. Many of the crimes that sex offender status are brought for, arnt really all that horrible. (like public unrination, or statutory rape in some cases)
I don't agree with pinning scarlet letters on people.
