FL Girl I think you are missing the point. First of all an airplane coming in for landing at 200 miles per hour is in no way the same as a helicopter hovering. So comparing an aiport flight path with hovering helicopters is pretty far of a stretch.
Second of all, you are missing the point that if the women at age 69 years old, hit that chopper 3 times within inches of each shot, bam, bam, bam, all the hits were right there together, they had to be rather low. If they were high in the sky way above the tree tops she could not have hit that many times that close together. We aren't talking about a military trained combat soldier with a sniper rifle. We are talking about a pissed off 69 year old grandma.
Thirdly I really doubt she ran out and started shooting the first time they flew over which tells me that it's gone on often enough for long enough periods of time for her to get mad, go get her gun, load it and then go out and shoot. I really doubt she was out there in her rockin chair waiting on them.
One last point that is being missed, how far should the cops be allowed to carry their "marijuana war"? If they can hover right above your property, what's to stop them from hovering there and looking in your second story windows? Maybe they'll stop at random door to door searches. How far is too far?
