Anthony Sadler, a Sacramento State senior who helped stop a possible terrorist attack in France appeared on The Tonight Show Starring Jimmy Fallon.

Sadler said he was sleeping on the train while traveling with Spencer Stone and Alek Skarlatos when he heard gunshots and glass cracking and the gunman walking in cocking his AK-47. This made Sadler respond by asking himself “is this real? Is this a joke?”

One of his friends said “go” and they moved toward the gunman.

“My friend Spencer got up, ran; my friend Alek got up and ran, so then I got up after I saw them go and I fully expected a gunshot to go off before we got there but it just never did,” Sadler said. Thank God. Spencer hopped on him. A few seconds later, me and Alek got there and we got to beat him down on him a little bit.”

After that, Sadler made a joke saying they almost stayed longer in Amsterdam because of it being a beautiful country and nothing else.

“You’re taking photographs and taking in the art scene. So you wanted to stay a little extra,” Fallon said.

Sadler told Fallon the entire moment lasted between one to two minutes.

“Not only is your dad proud and Sacramento proud, but the United States is proud and every country is proud,” Fallon said. “Thank you and you’re a good man.”
