I went through the Madison Wisconsin airport yesterday. Had some art paint brushes in my carry on tote bag. They scanned the bag twice, took out the brushes, LOOKED at them and SCANNED them, AND swabbed the inside of the tote bag. Said they dont see many brushes come through. I thought, GEEZ, how many times to you have to see a brush before you recognize it? And when was the last time they were a threat?
If the pen is mightier than the sword, and a picture is worth a thousand words, imagine what a terrorist could do with a paint brush!
