Justin, as to the wardens, most I have met are very professional, and courteous. But occasionally, you will run into a fecal ball.
The guy who had the birds killed, was one such. He could have waited to check on the records, and then made his confiscation, or just let things be, if the paper work was correct. But he has a badge, and a gun, and the feeling of power, with the Government backing him, right or wrong. It is a shame he is so ignorant, and in fact just plain mean. He definitely has some issues.
As for Native Americans being harassed by airport officials, refer back to the section on DMV personnel.
It is sort of like the Draft during the sixties...... I had a Friend from South Carolina, who was legally blind. His glasses were litterally like the bottoms of coke bottles. But he fit for combat. Are alive, and moving, you are fit for combat.
