A recent audit of the Baltimore Police Department (https://assets.documentcloud.org/documents/3009376/BPD-Findings-Report-FINAL.pdf) concluded "intentional discrimination" by the police. This has been a big point of anger for the Black Lives Matter movement and social justice warriors of all kinds, groups which generally clash with libertarians, especially the more conservative.
Should police keep to ideals and not stray to pragmatism in the name of order? If a group of people is committing disproportionate amounts of crime, is it legitimate to target that group disproportionally? Is this a sign of things getting worse or better?
