Because these are administrative searches. When you purchase a flight one might not always read the fine print. It is published on the TSA website also. It is more of an inconvenience than a violation. Administrative searches are those that you are subjected to “IF” you want to fly. If you don’t want your bag checked to can use another form of transportation.
