You're right. In the early nineties when I was at school, a friend of my mum was murdered by someone who had severe mental problems. Was too young to make the link with government policy then, but growing up it was obvious, especially after Jonathan Zito was killed by someone who should have been receiving treatment via ‘care in the community’ all the Tories were doing was cutting cost and releasing people who need care under supervision.
Every few couple of years this happens, nutter on a bus, crazy person with a axe, phsyco kills his ex at her workplace... all make great headlines for the mail, normally happens to ordinary people in public places. Often reported as random freakish events.
You can see why they would do it; none of the released people were going to live in the affluent areas where they live/work and it saves millions of pounds. Politicians often skip over are the real causes of problems. Especially the ones they create.
