It is dangerous to start a naming and shaming campaign John Griffin, Manchester

I would like to praise the efforts of Mr Kenyon in helping to expose paedophiles that slip through loopholes. Outstanding work. Please keep it up.
Steven Tunnicliffe, Plymouth

I am shocked at how many loopholes there are in the law these days. The most shocking was that people on the sex offenders list can still take in pupils when self employed. Surely there is something the government can do about this?

In tonight's programme it seemed you were giving paedophiles the help to dodge the police and the register. I found this hard to listen to. Could you please take this in to consideration as am sure many other parents think this.

I was shocked to see a BBC programme clearly promote witch hunting of people in our society. Whatever their wrongdoing, it is dangerous to start a naming and shaming campaign. This is the sort of reporting I only expect from the worst of our gutter press. It is irresponsible and I urge the commissioning editors to put an end to it.

Everyone has the right to know where danger lies Jenny Burchell, Herne Bay

I was shocked to see your programme on paedophiles on at such a family hour. My 10 year-old son was watching it. I am no prude, but the content I saw was totally inappropriate for the time of day. I did not realise that this subject matter could be discussed in such depth before the watershed.
Jennifer Russell, London

I was absolutely astounded that the BBC would show such a sensationalist expose of paedophilia. The show last night was as embarrassing as it was lacking in facts. Programmes like this pander to a tabloid hate mentality, and are not fit to be shown on the BBC.

Most clubs are now trying their best to ensure that young people can play sport in a safe environment and that parents can be confident in encouraging their children to take part in sport within a club environment.
Greg Wade, Coventry

I am shocked by the lack of safety the sex offenders register offers. Everyone has the right to know where danger lies. It is essential that the government do something about these major loopholes.
Jenny Burchell, Herne Bay

I was shocked to see on this programme the story of the man who was convicted in Australia. What shocked me most was the fact that the programme was unable to show his face because of his mental situation. What is the world coming to when it seems that programmes are more interested in protecting a person's identity then protecting the interests of children? With his face protected it leaves him open to abuse more children.

Our children are precious Joy Briars, Wrexham

As a teacher trainer I was appalled at the fact that until this year trainees could be sent into schools with no police checks. Calls to the DfEE resulted in stalling tactics, then the promise of the CRB checks. This year checks were a complete disaster. Some of our trainees are still awaiting clearance and have been with children since October. A solution would be to provide a date for the acceptance of applications for PGCE places so enough time is allowed for checks.

What is most incredible is that the programme showed thousands of sex offenders all the loopholes, to avoid being put on the sex offenders register.
Garto, London

After the Waterhouse Enquiry it is horrific to see how easy it is for paedophiles still to escape the sex offenders register. I hope you can lobby the government to tighten the law. Our children are precious.
Joy Briars, Wrexham

I am shocked that our judicial system seeks to protect the offender instead of the victim. The government seems to be trying to avoid upsetting these poor misunderstood people who prey on children. The government is still not facing up to its responsibility to protect the innocent and not the so-called civil liberties of these people.
