Why are people so afraid?

I just spotted this news item on the BBC news website. Obviously people are scared because they continually hear in the news how mental health patients run around with axes chopping off other peoples heads. Once again the stupidity of the general public leaves me speechless.

Also on the same day I have found this report which clearly shows that the main problem of mental health patients escaping is that they are a danger to themselves. Of course the answer to this is not a higher fence, but staff who are actually willing to do their jobs and supervise the patients.
