Many on the left appear to not have a problem with violence if it’s being used to further their political agenda. Not only are they willing to actively engage in violence, as demonstrated by the riots in Berkeley, they apparently also don’t mind embracing convicted terrorists.

For example, before Obama left office, he commuted the sentence of Oscar Lopez Rivera, a far-left Puerto Rican terrorist, letting him out 30 years early. Despite his past crimes, many liberals consider him a hero and are eager to celebrate his release.

According to reports, Rivera was expected to get out in 2051, but on January 17th, 2017, three days before President Donald Trump took control, Obama commuted his sentence, removing over 30 years. Thanks to him, Rivera, who got out of prison on February 9, is now back home in San Juan, Puerto Rico where he has been on house arrest serving the remainder of his shortened sentence, which is expected to end on May 17.

Once Rivera’s sentence is officially over, cities across the country are expected to honor and celebrate him as a hero. On June 11, participants in the Puerto Rican Day parade are planning on recognizing him as “Procer de la Libertad,” which is Spanish for “National Freedom Hero” during their annual event.

One of his most vocal supporters is Sen. Bernie Sanders (I-VT). Last year, he tweeted, “Oscar Lopez Rivera has served 34 years in prison for his commitment to Puerto Rico’s independence. I say to President Obama: let him out.” Once his sentence was commuted, Sanders showered Obama with praise. Specifically, he tweeted, “I appreciate @POTUS listening to Puerto Ricans and people worldwide who believe Oscar Lopez Rivera deserves a chance to enjoy his freedom.”

However, despite the left’s support for him, given his past, it seems inappropriate to call him a hero. It seems his fans either don’t know their history or don’t mind embracing someone the U.S. government has considered a terrorist since 1970. Back then, Rivera was an active member of the Puerto Rican Armed Forces of National Liberation (FALN), a violent, leftist rebel group that was fighting for the island’s independence.

During the 1970s, FALN engaged in more than 100 bombings across New York, Chicago, Washington D.C., and Puerto Rico. One of their worst bombings took place in 1975 at Fraunces Tavern in New York. There, four people were killed and more than 60 were injured. An image of the aftermath can be seen below (Warning, graphic content):

As a member of FALN, Rivera was involved in a number of crimes. In 1976, Chicago police discovered an apartment he owned filled with explosives, bomb-making paraphernalia, weapons, disguises, photographs of Chicago buildings he was considering bombing, maps of the city, and FALN documents detailing specific guerrilla warfare tactics the group used. He learned about this and didn’t return to the compromised location, becoming a fugitive.

A few years later, he was arrested after running a stop sign and providing the officer who stopped him with a fake Oregon driver’s license. After being arrested, Rivera declared himself a combatant in an anti-colonial war against the U.S. to try and be treated like a prisoner of war. As a captive enemy, he argued that the U.S. wouldn’t be allowed to try him as a criminal, and instead, would have to send his case to an international court.

Bemused, U.S. officials ignored him and sentenced him to 55 years in prison in 1981 for several felonies, including “seditious conspiracy.” Then, in 1988, he was sentenced to an additional 15 years for “for conspiracy to escape [from prison]; to transport explosives with intent to kill and injure people; and to destroy government buildings and property,” bringing his total to 70 years behind bars.

Unsurprisingly, the victims of FALN’s terrorist attacks feel much differently than Rivera’s supporters. Diane Berger Ettenson, who was six months pregnant when her husband was killed at Fraunces Tavern, can’t understand the support that Rivera has gathered. “I’ve had long hours in the middle of the night trying to figure out what I am missing, why he has all this support,” she told reporters.

Joseph Connor is also struggling with the glorification of a convicted terrorist. “Every time I have to defend my father’s life, it takes a little more of my life away,” he explained, adding, “my kids never met my dad, but they certainly had to deal with this. We never asked for it.”

Those celebrating Rivera’s release should be ashamed of themselves. He should not have been let out of prison. By releasing a convicted terrorist early, Obama has put other people’s lives in danger.
