No, I am saying that you stop and search those where you have a reasonable suspicion. If the eye witnesses say it was a black male, then stop and search black males.
If they say it was a white elderly female, stop and search them.
But we are not talking about a specific scenario as that, are we? In your initial post, you talked about police conducting random stop and searches - that is the very opposite of a targeted stop and search policy, based upon reasonable suspicion by virtue of evidence.
And as SP points out, and your own article suggests - black people are disproportionally stopped by the cops in stop and search operations, and you have to conclude it is because of the colour of their skin - this should not be the predominant reason.
