Here is how it works- You check the bag, the TSA inspects the bag and finds a nice camera. The agent steals the valuables, but does not want you reporting the camera stolen, because it could lead to them being suspected. After all, that agent steals 10 valuable things each day. So after stealing your camera, the TSA agent removes or changes the ID tag on the bag, and switches the routing tag, so it will go on a random flight. Instant lost luggage.
