"...One must have been convicted of a sexual related crime in order to be on a sex offender registry..."

WRONG!!!

In fact the police regularly get people onto the sex offenders register for life because they have a caution. This is most definitely NOT a criminal conviction.

They basically tell whoever they have in that if they accept a caution for the alleged rape/child porn/flashing etc. etc. they will get off. If they don't, the CPS will prosecute and their name will be all over the papers, people will hunt you down mate, even if you get off and you don't want that do you?

What do you do? Especially considering most people, only find out that they are on the Sex Offenders Register after they have accepted the caution.

The really shocking thing is that most of the time there is little or no evidence and the CPS wouldn't take the case anyway.
