Having known someone well that once shared a house with the Krays, I can assure you neither they, nor the Richardson's, targeted members of the public or armed forces at random, nor did they blow kiddies to pieces with bombs in very busy public arenas. They were career criminals, not terrorists, and often spoken of fondly by elderly members of the public in their locales. I would be extremely surprised if the supermarket machete man was a career criminal, or trying to rob the place. It looked a classic case of causing terror amongst the English public at large. If he indeed has the popular "mental health issues" it's remarkable how many black men currently seem to share his condition, one which possesses them to kill and maim for specious reasons with bladed weapons. I don't recall this phenomenon in earlier times, nor a long line of them being treated for anger management back then. It's becoming a modern day cultural thing and one which is now depressingly rampant.
