They would have a hard job to knock on my door, the flat I live in has a door downstairs for visitors, 3 other tenants also live by me. Must say it's good we have security, as I live in a big Tourist Attraction place. Great place to live in, there are plenty of shops, even a garden centre.
They employ young people with degrees of special needs too.
It's horrible to think these scumbags pray on people as they do.
