Summary: I show that the de facto police practice of constant random harassment by carding and other means, combined with less frequent unprovoked executions and prosecutions using false charges, in containing groups targeted for containment is exactly the most effective and efficient strategy for hierarchical containment developed by evolution and described by primate anthropologists. As such, the said practice should be understood to be an intrinsic feature of the societal dominance hierarchy. The harm from this practice can be mitigated using further knowledge from primate anthropology, to lower the hierarchy gradient and produce a net societal benefit (and less senseless violence). Cops are apes, not pigs.
