I agree to a point, but you should still not fire wildly ever, especially in a populated area.
If she could not find a target, she should not have shot the gun. Even suppressing fire requires knowing in general what youre shooting at. In this case, she should have dragged her partner to cover, called in the "attack" and maintained sight lines, looking for the danger. No bullet should have left her gun.
Acorn boy needs to be prosecuted for gross neglect and maybe even attempted manslaughter. I think she needs to be fired for poor judgement.
