I saw those ICE footage and it seems those officers don't hesitate to draw their weapons. I get they feel their life could be in danger when there's someone behind the wheel, but surely you'll know if you shot straight in the car you're going to kill someone? I dunno, they could have stopped the vehicle by shooting say the tyres?
If they were properly trained. I don't think they were though. Sadly, with it being political, the truth will likely never come out.
