Airport Security?

Currently, I am sitting in the San Francisco Airport waiting for my flight that will depart in about an hour. I've been here since 5:30. Despite the terrible layover, I enjoyed my time by eating a bowl of soup while reading Harry Potter and the Order of the Phoenix, a classic, and listening to a mixture of Arcade Fire, Dawes, and Neutral Milk Hotel. Around 7, I finished my soup and decided to go sit at my gate and await my flight. When I found gate 88 I sat at the end of a row nearest to a Pete's Coffee and Tea so that I could sufficiently contemplate whether or not I needed a chai tea latte (I did). While contemplating I saw a man that had to be the model for the old guy from Up walking towards me with two suited personal following him. Now I was a bit surprised by this as it seemed like the little old man was doing nothing wrong. Despite this, the personal seemed determined to catch up to him. As this was happening a man who was sitting clear across the room came and sat near me, prompting me to think "WTF." But I ignored this gesture in order to see what these suit-clad strong men were after.

I realized I was wrong about the mens' target when they passed the man from Up and instead continued to the row of seats in front of the one I was perched on, reading. They proceeded to ask about the suitcase that was under the seat in front of me. I told them it was there when I got there (I actually hadn't noticed it until they mentioned it). The creeper who followed me explained the same thing. One of the suited men poked the bag with his foot prompting me to think "hey, I don't want to be anywhere near this bag" at which I moved clear across the room. The creepy man followed me. I only shook this man once I got up to "go to the bathroom" and when I returned I sat as far away as possible. Now, while I was away, the suited men had moved the suitcase to an empty service desk where it remained unattended   (strike one) for about a half hour (strike two) until a large man in yet another suit came to examine it. Now, I am no expert on airport security, but wouldn't it make sense that if there was a suspicious bag sitting alone at an airport that it would be seen as a matter of relative threat and importance? Call me old fashioned, but isn't this the subject of what those annoyingly chipper voices that come over the loudspeaker every 20 minutes say over and over again?

Maybe I am being paranoid but, check out the damn bag.
