Kerik: NYC best-prepared city for New Year's threat

Former New York City Police Commissioner Bernard Kerik said Thursday the city is better prepared than anywhere in the world to keep revelers safe at a time when public terror attacks are top of mind for law enforcement officials.

New York City officials expect about 1 million people to ring in the New Year in Midtown Manhattan, raising significant security concerns in the wake of attacks by Islamic militants in Paris and and assault by a husband and wife inspired by the so-called Islamic State in San Bernardino, California.

"We have the most resources. We have the best training. And we've been through these types of things in the past," he told CNBC's "Squawk Box."

Kerik noted that the number of police stationed in and around Times Square has doubled since 2000, rising from 3,000 then to nearly 6,000 this year. That presence will include a number of plainclothes officers moving through crowds, as well as bomb detection officers, investigators and detectives.

"Plus the equipment that they have and the resources they have today that they've never had before, it puts us in a far-better position to secure the event and God forbid, to respond to some catastrophe in the event that something happens," he said.

New York City officials say they have received no credible threats to the event, NBC New York reported.

Officials in Paris and Brussels canceled New Year's fireworks displays amid heightened tension after the Nov. 13 attacks in the French capital carried out by Islamic militants, some of whom lived in Belgium.

Belgian police detained six suspects in connection with a plot to carry out an attack on New Year's Eve.

Kerik briefly served as interior minister of the Iraq Coalition Provisional Authority after the Iraq War and was nominated by President George W. Bush to lead the Department of Homeland Security, but Kerik withdrew his nomination.

He was sentenced to four years in prison in 2010 after pleading guilty to felony charges that included tax fraud and making false statements to the federal government while being vetted for senior positions.
