There is a lack of consequences or fear of in the UK now. When I was in year 6 at primary school we still had corporal punishment, my year 6 teachers attitude was, if you can't do the time, don't do the crime. Point of note, I can't remember anyone crossing the line and getting caned.
Arguments about corporal punishment aside, we KNEW there were consequences. These days people just do stuff knowing they are pretty much untouchable.
Back ground checks for jobs are undertaken by the poilice in part, so no wonder the wrong people get in or slip past those checks.
Actions or misdeeds HAVE to come with consequences that are actually going to have some sort of impact on you the abuser AND for the victim who feels that justice has been served and they and others are now safer.
It seems to me a lot of criminas just cry to the ECHR about being punished breaches their human rights, why cam't victims of CRIME sue the people who target them for human rights abuses.
