It also bears mentioning (and we really should emphasize this more) that most of the rounds discharged, including those fired in the 2 second window that Vyxn's upset about, were
rubber bullets or bean-bag rounds, not lethal rounds. They were used to break windows for visibility into the vehicle.
When they're a dangerous felon who poses a threat to officers or others? Yes. Already linked the US precedent for doing so.
But you haven't actually established that they
did use lethal force until he went for a gun. Again; the earlier rounds you're so bent out of shape over were rubber bullets. There were 4 bullet holes in the truck; three from an officer firing from the barricade, and one other from another officer, none of which were fired in that time frame or were involved with the window you keep bringing up.
