Comparing hearing a clap to a GUNSHOT is wild.
Ninety nine percent of people including you and everyone on HN would, if involved in a scuffle with an aggressive armed man would respond to a sudden gun shot by shooting the armed guy.
Yes you would respond to sudden gunshots with gunfire.
Yes agreed. Someone yells “gun gun” and they reacted thinking they were being shot at by the armed man that started an altercation with them.
But they heard "gun" and assumed it was the man who had been disarmed in plain view, and was being held down to the ground by 6 other agents. That's pathetic and disturbing. If he is that scared, he has no business holding a gun, let alone a job as a federal agent.
