To me this is obviously unethical, but wouldn't this also be obviously unconstitutional in the US? At least if done deliberately? 14th amendment and all that.
First consideration would be applicable legal standard, which practically always errs on the side of the State, second is the reasonableness of statistical methodology presenting the locations based on crime statistics.
I would not personally argue for its constitutionality, but given the precedents stemming from pretextual patrolling cases, it isn’t as clear cut as one might hope.
