NEW YORK (KTLA) -- One day after it was revealed that President Obama will not release post-mortem photos of Osama bin Laden, the commander-in-chief visited New York's ground zero to mark the 9/11 mastermind's death.

Obama made a stop at Engine Company 54, which lost 15 firefighters in the terror attacks on September 11, 2001 before heading to ground zero for a wreath-laying ceremony.

The president shook hands with firefighters and thanked them for their hard work.

"This is a symbolic site of the extraordinary sacrifice that was made on that terrible day almost 10 years ago."

"It didn't matter who was in charge, we were going to make sure that the perpetrators of that horrible act -- that they received justice," Obama said.

Obama had invited former President George W. Bush, however, a spokesman said he would not attend since he has chosen "to remain largely out of the spotlight."

Meantime, Obama said on Wednesday that he would not be releasing photos of bin Laden's body, which are said to be very gruesome.

There are "a lot to choose from," and most are "very graphic," a senior government official said.

CBS News reports that a bullet opened bin Laden's skull, exposing the brain, and also blew out his eye.

Republican House Intelligence Committee Chairman Mike Rogers told CBS that releasing the images could complicate things for American troops overseas.

"Conspiracy theorists around the world will just claim the photos are doctored anyway, and there is a real risk that releasing the photos will only serve to inflame public opinion in the Middle East," Rogers told CBS News.

"Imagine how the American people would react if al Qaeda killed one of our troops or military leaders, and put photos of the body on the internet," he continued. "Osama bin Laden is not a trophy -- he is dead and let's now focus on continuing the fight until Al Qaida has been eliminated."

In a recent poll, 80-percent of KTLA viewers said they want to see the photos.

Osama bin Laden was not armed but did put up resistance when U.S. forces stormed a compound outside Islamabad and killed him, White House spokesman Jay Carney said Tuesday.

Some other post-attack photos from inside the bin Laden compound have found their way to the Internet. Though they do not show bin Laden, they do show three other men killed by U.S. forces.

Two of the men in the photos, acquired by Reuters News Service, are dressed in traditional Pakistani garb. A third is dressed in a T-shirt. All have blood streaming from their ears, noses and mouths.

The photos were taken roughly an hour after the U.S. assault on Osama bin Laden's compound in Abbottabad. They were taken by a Pakistani security official who entered the compound after the early morning raid on Monday. The official then sold the photos to Reuters.

WARNING: THE PHOTOS ARE VERY GRAPHIC

White House spokesman Carney, reading a narrative drawn up by the Defense Department, provided new details of the events that transpired early Monday when 25 U.S. Navy SEALs in two Black Hawk helicopters landed outside the compound in Abbottabad, about 50 kilometers (31 miles) north of Islamabad.
