My proposed solution... framing of it... problem statement? Can you stop making everyone one of your posts cryptic and make your points clearer if you wish to have a discussion.
I didn't bring my crayons I'm afraid, but I'll try and explain it as simply as possible, but sadly words all have different meanings, and a lack, of understanding of language isn't a problem with the explanation.
Black people are overrepresented in crime statistics, so would likely be overrepresented in stop and search.
Black people are not overrepresented in crime statistics because they are Black. Being Black is not a cause of criminal behaviour.
Black people, instead, are overrepresented in poorer areas, and within certain types of family structure that do have a known causal link to crime.
This is why your suggestion that directly links being Black with criminal behaviour is a classic racist dogwhistle. It implies a link between race and criminality that doesn't exist, grouping individuals into a collective and assigning characteristics to that group incorrectly.
