Wearing black jeans and a shirt decorated with a Puerto Rican flag pin, the 74-year-old grinned and waved to cheering supporters through a fence at his daughter's San Juan home before getting into a jeep.
Escorted by the mayor of Puerto Rico's capital and other backers, he was scheduled to stop at a federal building to return electronic tags that monitored his movements during his home confinement.
Through a fence, Lopez told El Vocero newspaper: "If we love this country, we have an obligation to defend it." Lopez was considered a top leader of the Armed Forces of National Liberation, or FALN, an ultranationalist Puerto Rican group that claimed responsibility for more than 100 bombings at government buildings, department stores, banks and restaurants in New York, Chicago, Washington and Puerto Rico during the 1970s and early 1980s. The FBI classified the Marxist-Leninist group as a terrorist organization.
Lopez, a Vietnam War veteran who moved from Puerto Rico to Chicago as a child, wasn't convicted of any role in the bombings that killed six people and injured scores, but those who lost loved ones hold him responsible.
"This guy was convicted of leading the FALN that murdered people," said Joseph Connor, whose father, Frank, was killed in the Fraunces Tavern attack.
