My take on what is clearly murder: a bunch of insufficiently-trained ICE agents dog-pile — and subdue — the victim with multiple guns drawn (why were the guns out?!). One of agents accidentally discharges his improperly-drawn gun, spooks the rest, and then they all unload in to the unarmed victim.

Entirely possible other videos will show something else/more. I think it's also possible one of the agents was pistol whipping the victim with his gun which might have caused it to go off. Unbelievably reckless; depraved indifference.
