So nothing to link then? As from what I can see, the studies that have been done show no real effect on the prevention or deterrence of crime20% of those stopped and searched in England and Wales are found to be committing an offence. For what is potentially a minor inconvenience, minus the innocent buggers that repeatedly get stopped, I'd say that's a pretty good trade.
One of the key points that people who argue against it keep missing is that sometimes crime detection rates drop when it's not used.
Well of course they do. If you don't look for crime you won't detect it...
Discussion and conclusions
Overall, the analysis presented above suggests that, although S&S had a weak association with some
forms of crime across London between 2004 and 2014, the effect was at the outer margins of statistical
and social significance (H1). We found no evidence for effects on robbery and theft, vehicle crime or
criminal damage, and inconsistent evidence of very small effects on burglary, non-domestic violent
crime and total crime; the only strong evidence was for effects on drug offences (H2 and H3). When
we looked separately at s60 searches, it did not appear that a sudden surge in usage had any effect on
the underlying trend in non-domestic violent crime (H4). In other words, we found very little evidence
to support any of our hypotheses.
I'd wager the vast majority of the "offences" that the 20% found were a bit of weed. So if we legalised weed, stop and search would be pretty useless?
