And in Hamilton, the local police service is denying that racism plays any role in the fact that its own stats evidence that officers disproportionately target, stop, question and collect the personal information of young black people in that city.
There's a fundamental fallacy in this claim. You are ASSUMING that blacks aren't disproportionately involved in crime.
If they are, and there is lots of evidence that they are, then even if police ignore racial factors entirely and act only on objective evidence of criminal involvement, you would expect police to disproportionately stop blacks, even where those stops result in no charges.
It seems you and BLM want the police to stop equal numbers of blacks and whites, even if the whites aren't doing anything suspicious.
In other words, you want random stops of whites doing nothing suspicious and you want blacks to be left alone even where they are in suspicious circumstances, all to meet some absurd quota.
That's just wrong.
Bring back carding. Only criteria ought to be suspicious circumstances and it's quite natural that a group that is heavily involved in crime would be heavily carded.
