you do realize not more than 15 years ago you could fly with a weapon in the cabin. I'm sure you're also aware of the violence statistics in Chicago after they lifted the handgun ban.
I did not know that. 15 years ago, I flew quite often, and I thought I had to check any rifles, shotguns, or handguns. I always had to do their "residue check" which was NOT RANDOM. LIARS! But please elaborate on carrying firearms in cabin at that time. Thanks!
