This would eradicate any possibility of paedophiles or child abusers being able to assume another identity, which is relatively easy to do.
If DNA was taken and then checked, any previous convictions would automatically show up. It wouldn't matter how many times they changed their names, their DNA would always reveal their true identity, so anyone with bad intentions considering applying for a childcare job would be put off because they would easily be traced.
Everyone wishing to work with children is obliged to make children's safety a priority. If having a painless mouth swab taken and DNA results recorded deters people from applying for childcare jobs, then I don't believe anyone could object to this, unless their intentions are dishonourable.
Something as simple as DNA testing would put people's minds at rest and let children have more freedom to join in social activities without their parents worrying. As a mother and teaching assistant I would be very happy to provide a sample of my DNA.
We have the technology and we should take every opportunity to prevent our children feeling unsafe and vulnerable.
