Now some of you may have read here that during recent travels I acquired a few pocket knives. For the flight home they were all securely wrapped and placed in my checked bag along with my EDC. My wife and I checked our bags together at Boston Logan airport, at the same time with the same agent who placed baggage claim bar-coded labels on the suitcases and sent them off on the conveyer belt.
We are subsequently going through TSA regular security - shoes off, laptop in a separate bin, pockets emptied and contents placed in tubs. When we get to the walk-through metal detector they pulled my wife off to the side. I go through the standard metal detector, but they take her about three lines over to their super-duper four-wall chamber where you stand on the footpads while it does whatever it does.

Meantime I went through the standard detector, and while waiting for all the tubs containing our belongings to come through their X-Ray inspection, I'm putting my belt and shoes on and trying to see what they're doing with my wife.
When she re-joins me we have all our belongings except for her purse, which along with several other items (not ours) after X-Ray have been pulled off the conveyer belt and placed on a table. A TSA agent takes them individually one at a time to a table and shouts out "whose bag is this?" When the owner claims it the agent searches the bag, sometimes removing the contents, while questioning the owner. When he got to my wife's purse we were standing near the table and she stepped forward to claim it. I was told to stand back. He went through the contents of her purse, asked her some questions, then handed at all to her. She put everything back in it. I asked her "what did he say?" He asked her if she had any "sharp objects or weapons". She said no she didn't. "Are you sure?" Yes she is sure. I thought the entire episode was strange.
While unpacking at home I opened my suitcase and found inside it a notice from TSA that they had searched my bag. Then when removing the bar-coded baggage claim tags from the suitcases I saw the claim tags were reversed - the one with my wife's name was on my bag, which contained my knives.
Do you suppose TSA X-rayed the suitcase, saw the knives, searched it, saw her name on the attached tag and then passed word to the screeners to perform a more-thorough-than-usual search? Or am I just being paranoid?
