I believe you, Jim. Respectfully, we are unarmed in Canada because publics generally feel no need for it.
Personally, I lost an engine in a twin at sight-seeing altitude over the hazy purple of desert and cacti and my only fear of Arizona then was rattlesnakes!
We all fervently wish that were true here. It's a far more serious issue in Southern Arizona then where I reside in the Scottsdale area.
Funny you should make your second point today as there's an airshow going on at Scottsdale Airport, which is only a couple of miles away, and we're being treated to F15s,F16s,and F18s going over our home at about 500'. A couple of the widow ladies in the neighborhood called me and asked if we were now at war!!
