Unlike some others, I have no objection to having a camera where ever you might reasonably find a law enforcement officer. Street corners, banks etc are all fair game.

Oddly enough I had good experiences with TSA at MDW this week. On Monday they were very polite when I didn't take off my non-profile dress shoes. I had no intention of standing on one foot trying to put my shoes back on. I had to go to secondary after I didn't set of the metal detector. They happily retrieved my laptop with no argument. They wanded me...Swabbed my shoes to check for explosives and waved me through.

Same nice treatment in LA for the return. At least they did not try to be intimidating. They were quite pleasant!
