I'm waiting for some more videos to surface, but it looks to me like ICE agents really messed up here.
Appears dude was disarmed before shots fired therefore not a threat given the 4 agents subduing him.
Most plausible scenario: Accidental discharge triggered agents to shoot not realizing the dude was disarmed.
But it's also very plausible some trigger happy douche decided he was a threat and opened fire.
Neither are good.
On the spectrum of potential scenarios, at minimum anyone who fired a shot needs badge removed. Government liable for civil damages.
Shooters potentially eligible for criminal charges pending more evidence. What's shown, they can't do criminal charges to me.
Best thing feds can do is say they focked up but I'm sure they have a bunch of lawyers telling them they can't say that.
