The Bloomberg Legacy Examined

The mayor’s aggressive approach to gun control reaps results:

In 2008, even as gun killings fell, the number of killings committed with knives or other “cutting instruments” rose 50 percent in New York City, the Police Department said: to 125 from 83. Some other large cities saw no such increase last year, and police officials and experts are at a loss to explain what is either a new trend or a spike.

“It is hard to say with certainty what accounts for the increase,” said Paul J. Browne, the chief spokesman for the New York Police Department.

It was possible, but hard to document, Mr. Browne said, that measures like undercover gun-trafficking investigations and interrogations, in which people arrested for lower level crimes are asked to provide information on gun cases, had led to the rise in knife killings and the drop in gun slayings.

In 2008, 292 people were shot to death in New York, down from 347 the year before, continuing a longtime slide in deaths by firearms.

Over all, homicides of all kinds rose slightly last year, to 523 from 496 in 2007, which was a 45-year low. So far in 2009, about a quarter of killings in the city have been committed with knives or other cutting instruments, about the same percentage as in 2008. But the overall homicide rate is down: 97 through April 16, the Police Department said, compared with 135 in the same period in 2008.

“We may have made it harder for killers to get their hands on guns,” said Mr. Browne. “Knives are still easily and legally acquired.”

Is that really the coordinated message?
