For every action....
I was flying with another couple from SJC to AUA, connecting through BOS. One of them is a trade show specialist who contracts to companies to set up booths at the shows. No issues boarding at SJC. When we connected at BOS, we had to go back through security. She got held up for the longest time.
Why? Because she had a BOX CUTTER in her carry-on, that she had taken on many post 9/11 flights. Now you could congratulate the BOS TSA folks, but what about the SJC and many others that totally missed the VERY WEAPON used to take over the 9/11 flights.
I didn't feel much more secure after this...
