The NYPD stresses there is no specific threat against New York City, but has added extra patrols at 50 locations in response to the seemingly religiously motivated murders in Toulouse, France.
"It's a horror, it's a horrible thing that happened and it's a huge tragedy," said Helen Wolff. "People have gone crazy in this world."
There has been outrage in the city's Jewish community over the horror thousands of miles away. Officials in France say a gunman riding scooter opened fire at a Jewish school in Toulouse, killing a rabbi, his two young sons and a 7-year-old girl.
Now, 100 extra officers are under order to keep watch in Jewish neighborhoods around the city as well as at specific locations including the Museum of Jewish Heritage, the Israeli Mission to the United Nations and the 92nd Street Y.
"We're concerned about the so-called copycat syndrome, where someone might see the events unfolding in Toulose and take it upon themselves to act out," Police Commissioner Ray Kelly said Monday.
"There are individuals out there who hate and if they thought they could get away with it, they would do it today," said Assemblyman Dov Hikind. "There is no doubt in my mind."

"When you don't apprehend terrorists, that sends a message to other terrorists that they can murder with impunity," he said.

In all of these shootings, the gunman escaped on a scooter.
