There's been a few interesting things cropping up re "Consensual" Stop & Search especially with regard to minors - yes 9 years olds are being asked to give their consent to being searched.'Consensual' stop and search is bullshit. With one or two exceptions, you either have reasonable grounds to suspect or you don't. If you do, the relevant statute gives you the authority to search someone. If you don't have reasonable grounds to suspect, the use of 'consensual' search is unethical, if not downright unlawful.
Another was fascinating, more an indicator of massaging figures though, a "Stop & Search" for Cannabis/drugs that does not turn up drugs but turns up cider can be recorded as a success.
Scottish S&S figures rival those of New York.
Can't find the links atm.
