CAMBRIDGE, Mass. (AP) -- Thousands of mourners -- including MIT students, faculty and staff, and law enforcement officials from across the nation -- have paid their respects to a campus police officer who authorities say was ambushed in his cruiser by the Boston Marathon bombers three days after the bombings.
A line of mourners stretched for a half mile, waiting to get into the memorial for Sean Collier. They made their way through tight security, including metal detectors and bomb-sniffing dogs.
Speaking at the memorial at the school's Cambridge campus, Vice President Joe Biden referred to the bombing suspects as "two twisted, perverted, cowardly knockoff jihadis." He said terrorists attack the United States to try to get it to abandon what it values most -- its open society and its system of justice.
He told the family of the slain officer that he hoped they would derive some comfort from today's memorial service.
The officer's brother, Andrew Collier, says he was "born to be a police officer and lived out his dream." He says his brother would have loved everything about this day -- including the bagpipes and the American flag.
Boston native James Taylor led a sing-along of "Shower the People."
