A quick* look at the relationship between #knifecrime offence rates and #stopsearch offence rates (2017/18 figures). First, here with all forces and the E&W avg.
MPS a clear outlier on both measures (note these are *rates* not totals).
[*not that quick to produce]

Now with the MPS and E&W avg removed. No relationship *at all* between the two measures.
So rates of #knifecrime do not explain rates of #stopsearch in general.

Really important point: 2017/18 was *before* the MPS started their 3x increase of #stopsearch, so SS rates in the Met are now *much* higher

Here's what the first chart looks like with the MPS 2019/20 figures added ( #knifecrime rate up 6%, #stopsearch rate up 110%).

*typo: they are stop and search rates, not stop and search offence rates.
