That may be possible about the weapon in the tree agents right hand.
I tried to see if I could see the discharge from firearms but couldn’t.
However that is how you fire a taser, I’m certain that’s exactly what happened. They ambushed him and were planning on killing everyone in that truck. They tried, I think the only thing that saved their lives was the arrival of the other officers.
All I know is that the agent on the right had to shoot first if I’m right about the taser. I expect I am.
