Crime is down but the city wants New Yorkers to be prepared for all kinds of dangerous situations. NY1 Criminal Justice Reporter Dean Meminger tells us about a new website advising New Yorkers how to respond to emergencies.

Unveiling the latest crime numbers, the NYPD says last month was the safest October in the city in more than 25 years . 

"We've never seen numbers this low," said NYPD Deputy Commissioner Dermot Shea.

But as Mayor Bill de Blasio and police brass tout just how safe the city is — the de Blasio administration also unveiled a sobering website called Plan Now NYC. It tells New Yorkers what to do in life-threatening emergencies ranging from an active shooter situation, to a terrorist attack with bombs or chemicals.

"This is not because we have some kind of threat that is imminent," said Commissioner of the city's Office of Emergency Management, Joseph Esposito. "This is about being ready for all things that can happen in this city."

Things like the Chelsea bombing, when a home-made device detonated on West 23rd Street,  injuring 31 people. A second bomb was discovered a few blocks away.

The city says first responders are constantly conducting drills for potential attacks, and they shouldn't be the only ones.

"We feel that the citizens that live and work in this city have to be equally as prepared to deal with, and to be ready for and to recover from a terrorist attack," Esposito said.

The new web site, run by the City's Emergency Management agency, says New Yorkers should practice the A-B-C rule for active shooters — avoid the shooter at first, if you can't do that, barricade yourself from the person. And if that fails, as a last option confront the shooter and fight for your life.

There are also instructions on how to stop bleeding if someone is injured in an attack.  

"We are a city that lived through hurricanes, nor'easters, 9/11 and that is not, when something like that is unfolding when you should be thinking about, how do I find the kids, where is a meet location, how do we communicate, what's our backup system," said NYPD Deputy Commissioner John Miller.

The head of Emergency Management says this is not a scare tactic but rather a reality check, he wants New Yorkers to be ready.
