NEW YORK, NY ( wkbw / wabc ) Channel 7's John Borsa met with Western New Yorkers who went to the "Ground Zero" site Monday after hearing the news that Osama bin Laden had been killed.

They, like many others, felt the need to go to the spot where the "Twin Towers" once stood...to remember those who lost their lives in the 9/11 attacks.

John Borsa was the only Buffalo television reporter to report from New York City after the announcement Sunday that a special operations force killed Osama bin Laden.

While on the scene, he met with New York City Police Chief Ray Kelly for his response to the news, and how security may change at the site.

NEW YORK (WABC) -- While there are no specific threats, authorities are on the lookout for signs of possible retaliation by terrorists.

"We're certainly not taking any chances," NYPD Commissioner Ray Kelly said.

A stepped-up police presence is evident across the city, from landmarks like St. Patrick's Cathedral to mass transit hubs like Penn Station and Grand Central. Heavily armed officers and K-9 units are on the lookout for signs of possible terrorist retaliation.

"You come out of a house of worship and then you see heavily armed men," tourist Yvonne Paredes said. "It's a little scary, especially in New York City."

"I'm a little scared, so I'm going to be very careful where I go over the next couple of weeks," straphanger Aaron Mintz said.

Some find the stepped up security comforting.

"You feel protected and safe," tourist Lisset Salazar said.

"I feel a lot better knowing that there's a lot of cops here and a lot of other people too," another traveler added.

Federal authorities say they have not fielded any specific threats, but they are warning police that Osama bin Laden's death may to inspire extremists.

"Our assumption is that bin Laden's disciples would like nothing better than to avenge his death," Kelly said.

Many New Yorkers, used to the understanding that their city has long been a target, say they have no choice but to get on with their lives.

"You can't feed into the fear, because if you do, then you can't leave the house," subway rider Ruth Phillips said.

Authorities also warn that bin Laden's death may inspire homegrown terrorists. At a news conference Monday, New York Senator Chuck Schumer said we have to monitor "the lone wolves."

Channel 7's John Borsa continues to report from New York City Tuesday on Eyewitness News at 5, 6, and 11. WABC contributed to this report.
