this is not true. why is this upvoted? first of all, ICE is federal. second, they were acting as part of "federal official" duties. it will be trivial to move any state prosecution to federal court.
They will certainly attempt to dismiss any charges, but they are far from guaranteed that they will be successful.
So is it part of their official duties to walk in front of a car of someone who is trying to leave the scene, alter their path when the car turns out of the way to ensure they remain in their way, and then shoot the driver? Or is that merely the kind of excessive force that's in contravention of their training and not part of their job role?
