Those numbers come from this recent CBS article:
NEW YORK (CBSNewYork) — Police Commissioner Bill Bratton is behind a controversial proposal to grant amnesty to more than 1 million people with open warrants for low-level offenses.

But some experts worry it could cause crime to skyrocket.

First he called for reduced penalties for smoking marijuana. Now, Bratton wants to explore granting amnesty to 1.2 million city residents with open warrants for low-level offenses, people who run the risk of being arrested for failing to resolve tickets for drinking in public, disorderly conduct and the like, CBS2’s Marcia Kramer reported Monday.

There is one statistic that shows the magnitude of the problem. Last year, of the hundreds of thousands of tickets that were given out for low-level offenses, fully 40 percent of the people either skipped the proceedings or didn’t show up, Kramer reported.

So if there are 1.2 million city residents with open arrest warrants, and there are only 8.4 million people who live in New York City, then it can only be that 1 in 7 New Yorkers have a warrant out for their arrest.

Police State much?
