New York, where murders are up 20 percent over last year, is also taking action to step up enforcement. It will launch its “All Out” program next week, deploying 330 extra officers to crime-ridden neighborhoods, The New York Times reports. That’s a month earlier than the program began last year.

But even with the increase in murders during the first five months of the year, New York still on track to finish 2015 at roughly half of the city’s murder rate in the 1990s, which routinely surpassed 2,000. (Crime in New York is also down 11 percent in other major crime categories, according to the Daily News, including burglary, robbery, rape, larceny, and auto theft.)

“What goes down generally comes back up,” says James Alan Fox, a professor of criminology at Northeastern University in Boston. “There are certain cities that have had short term spikes, but we would not be noticing it were it not for fact that we have seen some successes over the past few years.”
