Thousands gather to honor slain officer in New York

Vice President Joe Biden honored Rafael Ramos at the slain New York police officer's funeral Saturday.

He spoke of Ramos and his partner Officer Wenjian Liu, who were shot and killed Dec. 20, ambushed as they sat in their squad car.

"Being a cop was not what they did, it was who they were," Biden said.

Motioning to the sea of blue police seated in the church where the funeral was being held, Biden said, "It's who you are."
