squeeze off
ロサンゼルス国際空港で日本時間の今朝午前１時半ごろ、銃撃事件があり、米運輸保安庁（ＴＳＡ）の職員１人と犯人が死亡したとのことです。
squeezeは、ご存知のように「ぎゅっと握る、しぼる」ですが、the triggerを目的語にとると、それだけで「引き金を引く」という意味にもなります。
さらに副詞のoffが付いてsqueeze offというPVになると意味が強調され、「打ちまくる」というニュアンスが加わります。Websterには"to fire (a round) by squeezing the trigger"とあります。またまた…、銃（ライフル）惨禍です。ただただ悲しい…。（UG）
Chaos, terror unfold inside LAX Terminal 3: 'Gun. Everybody get down'
Pop. Pop. Pop.
What is that, a number of passengers at Los Angeles International Airport thought? Then came the screams from inside Terminal 3: "A gun. Everybody get down."
By the time the shooting stopped Friday morning, a lone gunman had squeezed off 10 rounds from an assault rifle, according to authorities, killing at least one person and wounding several more.
Hours later, with a wounded gunman in custody, those who survived the shooting rampage painted a terrifying picture of how the attack unfolded:
Everybody get down'
It was 9:20 a.m. inside the crowded terminal that serves Alaska Airlines, JetBlue, Spirit Airlines, Virgin America, Frontier Airlines and a number of other commercial carriers.
Dana Starfield was one of the hundreds of passenger waiting to clear security or board flights when the gunman, according to police, walked into the terminal, pulled an assault rifle from a bag and starting firing.
Then she heard a "boom."
"We heard someone scream, 'A gun. Everybody get down, get down,'" Starfield told CNN affiliate KCBS.
Many, including Starfield, had cleared one TSA checkpoint, where her ID and boarding pass were checked. She and others dropped to ground, near the security checkpoint.
"We just crawled through the security gate," she said.
Starfield said Virgin America employees guided her and several others into a small room, where they barricaded the door by moving a copy machine in front of it.
"We heard a few more booms," she said.
About 15 minutes later, she estimates, Los Angeles police SWAT officers came through and led them to safety.
