Spent the day in Vancouver last week with my sisters. As we were entering the US via car from Canada, we were discussing CBP, TSA, DHS baloney. The wait was about 20 minutes so we continued our discussion. At one point I mentioned something about a dirty bomb and what will happen with security measures when one goes off somewhere in the US. The words were barely out of my mouth when an officer and German Shepherd came sniffing around our vehicle then left. Was this a coincidence or are there listening devices at border checkpoints? Just curious.
