While critics are disturbed about New York City returning to its crime-filled, dangerous pre-Giuliani past under the liberal guidance of Mayor Bill de Blasio, the mayor himself says an uptick in knife attacks is actually a sign that his NYPD is improving the city.

“I’m not a criminologist,” de Blasio said of the slashings. “But I can safely say that guns are being taken off the street in an unprecedented way. Some people, unfortunately, are turning to a different weapon.”

Since the beginning of the year, there has been a 20% increase in the number of slashings – many of them random attacks by criminals using knives, razors, and other cutting implements. But while a correlation in reduced shootings would seem to provide some measure of support for the mayor’s argument, crime in general is way up in 2016. Furthermore, while shootings have fallen this year, they’re still higher than when de Blasio came into office.

Law enforcement experts who spoke to Fox News said that de Blasio’s crackdown on illegal guns had nothing to do with the rise in slashings:

“These criminals didn’t just start carrying knives out of the blue or because of the guns getting taken — I don’t believe that for a second,” former NYPD Detective Scott Prendergast, who runs the private investigation service Cornelius Investigations, told FoxNews.com.

Instead, Prendergast blames the rise in knife attacks on de Blasio for ending “stop-and-frisk,” a policy in which police officers stop people based on suspicion and frisk them for weapons or other illegal items.

The mayor campaigned on a platform of bringing those stop-and-frisk policies to an end, even though they were largely responsible for bringing the city back from the brink in the 1990s. Mayor Rudy Giuliani put the criminology theory of “broken windows” policing into action – a theory that involves a full-scale crackdown on minor crimes as a way of restoring law and order to a dilapidated city. It worked like a charm. By the time Giuliani retired, serious crime in New York City – including homicide, rape, robbery, assault, and burglary – had plummeted by 75%.

So why would anyone – even an idiot like de Blasio – want to stop the NYPD from doing what was so clearly working?

Racism, naturally.

Civil rights groups have said that stop-and-frisk policies unfairly target minorities, and that’s all a Democrat needs to hear. If there’s any evidence that more blacks and Hispanics are being stopped than whites, then nothing else matters. Even if it means turning the city back into a dangerous cesspool of violence, Democrats will not betray their core constituency. You know, even though those same minorities are usually the victims of these crimes.

Unfortunately, it’s not just New York City and it’s not just Democrats. Republicans are starting to embrace this movement towards decriminalization and lighter sentences; it’s apparently now more important to get criminals out of our prisons than off of our streets.

What could possibly go wrong?
