This business of sending federal troops into American cities over the objections of the city mayors and state governors is not something we normally see in the US, and lots of people are scared. Technically, ICE is law enforcement, not military, but the line seems to be blurry at the moment; ICE is perhaps something in between the two. ICE and the population are afraid of each other, and people do unwise things when they're afraid.
Nobody should be running people over in their cars. Also, a police officer doesn't get to shoot a civilian just because the civilian is sitting in a car.
Exactly what happened in Minneapolis and Portland needs to be investigated, as with any violent death, and I'll reserve judgment until the justice departments of Minnesota and Oregon have completed their investigations.
