I'm posting a rather late comment on this, in support of my earlier point about diabetics, as I just came across this article: Diabetic in coma tasered on bus http://www.dailymail.co.uk/pages/live/articles/news/news.html?in_article_id=494199&in_page_id=1770 Given that this was the police, who in general are fairly decent, the idea of profit motivated companies picking up anyone a bit incoherant, with an eye to a bonus, is surely now something that is completely unthinkable?
