In the interests of balance: certain segments of the young population in the UK feel the need to wear a knife at all times "for self-protection", with the inevitable accidents, headlines and moral panic. Nobody seems able to convince the youngsters in question that wearing a concealed weapon isn't directly equivalent to wearing a Kevlar vest.

This over here, and gun atrocities in the USA, both stem IMHO from the hero syndrome, which has been a millstone around mankind's neck since the days of the saga. I promise to blether on about it some other time, as this margin really is too small.
