My wife and I were in St. Louis for me to go to a job interview, and afterwards we stopped to pick up a new cat from an animal shelter. While we were at the shelter I had to run out and pick something up, and she stayed behind to do paperwork. But I took a wrong turn on the way back to the shelter and ended up on a highway going the wrong way, so I took an exit to the right and was going to circle back. But while I was on the exit ramp, I saw a plume of black smoke coming up from a large 10+ story office building as it collapsed.
By the time I made it onto the street from the exit ramp, there were police directing traffic/searching people and FBI guys in suits everywhere. I happened to be wearing my suit for the job interview, and I somehow got mistaken for an FBI agent. They were swarming everywhere so it was easy to get lost in the crowd. Apparently, it was some sort of government building. The weird thing is there were already bulldozers on-site cleaning up the rubble. Less than half an hour after the collapse.
Someone came by and handed me a UMP .45 with a magnified EOTech (I get the impression that the scope was mounted last-minute, as it was magnified and had the hold-over dots in the reticle for AR15 bullet drop) and told me to make sure nobody got close to the bulldozers. I walked over near the area with the bulldozers, and used the scope to look at the rubble. I saw something suspicious on the concrete bases that the giant steel structural beams mounted in. I walked closer when nobody was looking, and picked up a large metal/concrete box that had fallen out of the concrete base. It weighed about 40 lbs and there was a rod with a broken steel cable sticking out of it. When I lifted the box by the cable, the box vibrated, bounced up and down. There were oscillators built into the structure of the building, and when the oscillators were turned on they caused the building to vibrate at its natural frequency, and like a wine glass being shattered by the right tone, the building collapsed.
I discretely took some cell phone pictures of the concrete base, the oscillator, and the cleanup, then tried to look official with the UMP slung in front as I made my way out of the area with the oscillator bouncing in my hands.
And then I woke up. Did I go to sleep with the tinfoil on too tight?
