I think OP of the post is correct. Play the video in slow motion and watch the grey coat guy. He approaches with empty hands and appears to retrieve a weapon from the suspect’s back and is walking away with it before the first shot is fired.

So the suspect was likely unarmed when the shooting starts.

I think the gun was actually there, nowhere near being used, and they found it before shooting him.

My guess, someone saw a gun, yelled 'gun', and an agent assumed that must have meant that somehow magically the guy had a gun in his hands that he didn't see and just opened fire...

Or else he drew his gun to be prepared for a gunfight and pulled the trigger...

Or someone else made the case that the ICE guy who took the gun from the victim ended up discharging the gun into the ground as a first shot, and another officer heard that gunfire and just started blasting, with no idea where the shot was fired from or toward.

So in short, yeah, he had a gun on his person, in no way a threat to the ICE people since his hands never went anywhere near it, and ICE fired on him.

Terrible enough incident on its own, even worse is Noem lying to justify it and declare no possible wrongdoing or even improper procedure, and again they are impeding real law enforcement investigation..

I'm assuming these brainwashed zombies known as ICE, have been ordered to plant guns on protestors.
