A 600% increase in what was a tiny number to start with is not a "crime wave"

[adventured]

~500 acid attacks annually in London, growing as rapidly as it has been the last three years, is not a tiny number nor a trivial matter.

London has a lot of knife crime. A 24% increase in such a short amount of time is not a tiny increase in that either.

So from 80, to 500, in a population of almost 9 million?

That's not to mention that we need to look at numbers in a long term trend, looking at 1 or 2 years of data doesn't show the full story.
