I don't know anyone who would confuse the Department of Homeland Security with the Transportation Security Administration. I was erroneously placed on their watch list several years ago because of a common name; this meant no online boarding passes and positive id confirmation at the ticket counter for a boarding pass. It took several letters and affidavits sent to the TSA to be removed from the list.
9/11 changed the world forever and all of this is related to the OP and the severe supply and demand imbalance of firearms and ammunition, gun control, etc..
