Good. Glad we have folks aware and vigilant in public places that are more likely for terrorism. Especially in gun-free secure zones where you and I aren't allowed to have weapons to protect ourselves.They are watching movement and body language. Do not adjust or fiddle with it. I was at Bush waiting for my sons return flight. Had a kidney stent after having one removed. Was sitting close to a bathroom because every 5 minutes or so I had to go. I told my wife after getting up 4 times or so I would probably be questioned soon. Sure enough two full kit warriors with long guns (sbr) and a dog was at my 12 o'clock and just looking at me. I smiled nodded and got up to go pee again. They hung out for 5-7 minutes or so then disappeared into another part of the airport. This was not conscience.
