Shooter Watched Mass Shooting Videos Night Before, Wrote Manifesto Calling U.S. “Nation of Evil”

New reports reveal the Pensacola shooter Mohammed Saeed Alshamrani watched mass shooting videos at a party the night before he killed 3 and shot himself.

In addition, Saeed Alshamrani wrote a short manifesto calling the U.S. a “nation of evil” that was discovered in his social media.

Fox News reports the Saudi student who fatally shot three people at a Florida naval base Friday has hosted a dinner party the night before to watch videos of mass shootings, a U.S. official said Saturday.

The official, speaking on condition of anonymity, told the Associated Press that authorities told him one Saudi student was recording outside the building while the shooting took place. He said 10 Saudi students are being held at the base and that several others are still unaccounted for.

Mohammed Saeed Alshamrani, who was said to be a second lieutenant in a flight training program for foreign military personnel at Naval Air Station Pensacola, posted a short manifesto to Twitter where he claimed to be “against evil,” AFP reported, citing the SITE Intelligence Group.

“America as a whole has turned into a nation of evil,” the post reportedly continued.

According to SITE, a group that monitors jihadist media, Alshamrani allegedly wrote in this manifesto that he “hates” Americans for their supposed crimes against Muslims and “humanity.”

“I’m not against you for just being American, I don’t hate you because your freedoms, I hate you because every day you supporting, funding and committing crimes not only against Muslims but also humanity,” he wrote, according to the report.
