I've seen this in action during a ridealong with @MPSValentines.

Group of 5 stopped & searched outside a bookies.

One was found in poss of cannabis & was wanted for burglaries. Rest were free to go.

20% success rate technically but the resident complained about the group. https://twitter.com/KatClinPsy/status/1332973424273133573

This is why I always say policing stats don't necessarily reflect the true nature of policing and what happens on the streets. If a resident says someone has a knife and there's a group, you can't expect police to know who has the knife without a search.

And minimising a Class B drug as a bit of weed is minimising something that is still illegal.

If you want cannabis legalised, lobby your MPs - they are legislators.

Don't come after the police for doing their jobs.
