The rate of knife crime with injury, as recorded by the Met, has remained fairly stable since 2010. There has been a small but significant increase in overall knife-related offenses since 2010, but there is always the possibility that this has more to do with stricter enforcement than any baseline increase in criminal behavior. So knife crime is not really a good example of any kind of recent crime surge in London. See the first chart in this article:

(Note that the identification of Westminster as a knife-crime hotspot in the second chart is misleading, as this is an area of central London with lots of tourists and workers, thus inflating the number of crimes per the relatively small number of residents.)

Knife crime is a serious problem, but it’s not something that I worry about at all in my day to day life in London. It would be no more rational for me to do so (in fact, less rational) than it would be for a New Yorker to worry about being shot.

What I still don’t understand about this thread is why someone who doesn’t live in London has repeatedly being telling people who do live in London to “go out and see for themselves”. You seem very attached to a narrative about London found in certain sections of right wing online media, and unless you’re not telling us something, this can’t be because you have any personal interest in life in London. I feel like there’s some kind of agenda here, but I don’t care to speculate exactly what it is.
