Just to confirm what I'm saying, you say...
"Apparently, stop and search produces 1% more prosecutions amongst black kids than non-black, but of all people stopped, blacks make up 75%."
But if you check here you will see that it is in fact not true, it's around 35% of all people stopped

I'm not saying that the underlying situation isn't true, that black people are more likely to get stopped, but as always with these things people suck up statistics without checking the facts for themselves.
"You've totally ignored SP's main point that although 75% of stops are black there's only 1% more prosecutions. "
maybe because it was made up?
