Today Barack Obama visited Ground Zero, where he laid a wreath in memory of the nearly 3,000 people who died there on 9-11. In the wake of the killing of Osama bin Laden, there was fear of retaliation, so security was heightened.
There was a fleet of garbage trucks lined up to protect President Obama. The line of garbage trucks stretched almost a block long and created a barricade of steel as the President had lunch with New York's bravest, the heroes of Engine Company 54. Fifteen firefighters from the firehouse were killed on 9-11.
Security was increased for President Obama's visit to Ground Zero. Police were patrolling rooftops and mailboxes were removed from the surrounding area, and some manhole covers were sealed shut.
It was a bittersweet moment as the President laid the wreath at Ground Zero, remembering the 3,000 lives lost nearly a decade ago while celebrating the death of Osama bin Laden, the terrorist behind the 9-11 attack.
Obama solemnly bowed his head for the moment of silence. He shook hands with police and shared warm hugs with 9-11 family members. Crowds lined the streets, cheering for the motorcade.
But some weren't satisfied with the visit. Tim Murphy's brother was killed on 9-11, but he wasn't among those picked to meet with Obama today.
"With the assassination of bin Laden I wanted to shake his hand and say thank you, now my brother can rest in peace," said Murphy.
But for others, the President's visit marking bin Laden's death brings closure for a day the nation will never forget.
