In the aftermath of the December 10 shooting at Pensacola Naval Air Station by a member of the Saudi Air Force, who killed three U.S. sailors, 21 other Saudis are being sent home. 

The students being expelled were neither charged with abetting the crime nor with being involved with terrorism. They did, however, have “derogatory material” on their computers, mainly child pornography and anti-U.S. media. 

Saudi Air Force Second Lieutenant Mohammed Saeed Alshamrani, 21, acted alone when he began shooting at the U.S. base where he was undergoing flight training, FBI investigators discovered. Alshamrani was eventually killed by a sheriff’s deputy.

In the immediate aftermath of the deadly shooting, Senator Rick Scott, (R-Florida) said that the United States needs to review the procedures under which foreign students are admitted to the U.S. for training. Currently, there are nearly 5,000 foreign military students from over 150 countries receiving training in the United States.

 U.S. Attorney General William Barr said that while the shooter was“motivated by jihadist ideology” and that the attack “was an act of terrorism,” there “was no evidence of any affiliation or involvement with any terrorist activity or group.”

“Social media attributed to the shooter suggests that he harbored anti-U.S. military and anti-Israel sentiments,” FBI Deputy Director David Bowdich said. “[He] thought violence was necessary to defend Muslim countries.”

FBI investigators have struggled to unlock the shooter’s phone to see who he contacted prior to the shooting and have asked Apple to help in unlocking his data from the “WhatsApp” and “Signal” apps. Thus far, the computer giant has refused to help. Apple has said it would not assist the Justice Department by turning over private information from the gunman’s phones.

Following the shooting, the U.S. suspended all training for Saudi nationals while an investigation was conducted into this deadly act. On December 19, the Pentagon announced that there was no credible threat from the other 850 Saudi military students training in the U.S.
