A Coast Guard spokesman, Lt. Cdr. Scott McBride, confirmed on Wednesday that one of its service members stationed at headquarters in Washington had been arrested on weapons and drug charges, but declined to comment further on the case. “Because this is an open investigation, the Coast Guard has no further details at this time,” Commander McBride said.
Federal investigators said in the court filing that Lieutenant Hasson had begun stockpiling weapons in 2017. When federal agents searched his cramped basement apartment in Silver Spring, Md., they said, they found a cache of 15 assault rifles, shotguns and handguns and more than 1,000 rounds of ammunition that the lieutenant had amassed.
The Program on Extremism at George Washington University called attention to the court filing in Twitter posts on Wednesday. In the filing, the authorities cited writings found on the lieutenant’s computer that point to extreme racist and apocalyptic views.
Shortly after the violence incited by a white supremacist rally in Charlottesville, Va., in 2017, the authorities say, Lieutenant Hasson drafted a letter to a well-known neo-Nazi expressing support for the idea of building a “white homeland” in the Pacific Northwest.
“I never saw a reason for mass protest or wearing uniforms marching around provoking people with swastikas etc.,” he wrote. “I was and am a man of action, you cannot change minds protesting like that. However you can make change with a little focused violence.”
In a passage of the letter quoted in the court filing, Lieutenant Hasson wrote, “I am a long time White Nationalist, having been a skinhead 30 plus years ago before my time in the military.”
The authorities said Lieutenant Hasson had studied the 1,500-page manifesto that the mass murderer Anders Behring Breivik, a far-right Norwegian extremist who killed 77 people in 2011, wrote in the hope of inspiring other killers.
