There are two things that come to mind on this "implicit bias" issue.

First, there have been numerous studies demonstrating that racial bias or preference exists even in newborn and infant babies, even in the first months of life. They tend to prefer the company of humans that have a similar skin tone and are more reticent around humans with a significantly different skin tone. There might be a bit of an "original sin" thing happening where the social justice crowd is trying to pound a type of bias out of everyone that's built into the human psyche and cannot be removed any more than an aversion to spiders or to heights or whatever.

Second, it is a fact (and this is not to comment on the underlying causes at all) that the crime rate among black Canadians is fully 10 times higher than the national average. That's 1000%. It is hard, to say the least, for law enforcement to deal with that observation pattern for years and years on end without developing a bias, even if unintentionally.
