Thanks for sharing this, I hadn't heard of this.
Here's Teddy Roosevelt in his own words [1] describing it:
> To break up the system of blackmail and corruption was less easy. ... the criminal who is blackmailed has a direct interest in paying the blackmailer, and it is not easy to get information about it. Nevertheless, we put a complete stop to most of the blackmail by the simple process of rigorously enforcing the laws, not only against crime, but against vice.
...
> The multiplication of laws by the legislature and their partial enforcement by the executive authorities go hand in hand, and offer one of the many serious problems with which we are confronted in striving to better civic conditions. New York State felt that liquor should not be sold on Sunday. The larger part of New York city wished to drink liquor on Sunday.
> ...
> The law was not in the least a dead-letter; it was enforced, but it was corruptly and partially enforced.
> ...
> The paper again and again called upon the police commissioners to either uniformly enforce the law or uniformly disregard it.
