I could talk about how the Public Prosecution Service of Canada manages that issue. When an accused is indigenous, their situation is considered to see if it may have been affected by discrimination or racism.
As to the reasonable prospect of conviction, you're absolutely right. Bias and racism are not factors that we consider. In making our decision, however, if there is ultimately a reasonable prospect of conviction, but that prospect is not very strong, and if prosecution is not necessarily in the public interest, we weigh the pros and cons.
