How to Shut Down New York’s Unlicensed Pot Shops
In City Journal article, "How to Shut Down New York’s Unlicensed Pot Shops," the late Mark Kleiman is mentioned:
NYPD commissioner William J. Bratton made cracking down on squeegee men a top priority, issuing a clear warning that they would no longer be tolerated and instructing beat cops to arrest every squeegee man they saw. Squeegee activity collapsed. The late policy guru Mark A. R. Kleiman attributed this success to "dynamic concentration," the strategy of dedicating a burst of police resources to a significant problem, addressing it in every instance for a short period, and thereby effectively deterring future offenses, after which enforcement becomes a trivial issue
