@Colm You mention a poll of the people of London being in favour of a continuation of stop and search - do you have a link to that?
No one can have an argument with targeted or intelligence -led stop and search initiatives - but that is not what the statistics and studies show us. It is the s.60 searches that are the most contentious - those that are not specificallty targeted by intelligence but are,rather, a general power to stop and searc anyone a police officer feels like- and a detailed analysis of the figures shows that, whilst the use of s60 has declined markedly over the last few years, blacks in particular are disproportionately the target - Something like 23 times more likely to be the target than either a white or asian counterparts.

It is S&S under s60 powers that need moderation, especially when it comes to the MPS.
