Arizona and North Carolina are two. While there is no law (that I know
of) on their books specifically allowing the shootdown, the people who
did so never went to jail. In one case, a police helicopter was chasing
children in a park with their bird. The man who downed the copter went
to trial but was not convicted, the cops were. I think that one was in
NC. I don't remember the specifics of the AZ case, but it never went to
trial.

IIRC the AZ case was border crashers.
