It is undetermined whether all the guns reported missing at O'Hare were stolen there or at their destination airports. In Chicago, the only people who would know a gun is packed in a particular piece of luggage would work either for the T.S.A. or for the airline that checked the bag.
Many baggage handlers hired by United said they are dissatisfied with their working conditions and pay. They are paid about $7 an hour and do not receive tips and complain they have not had a raise in years.
So how to travel with a gun anymore? Drive. Ship it to your destination. Place all tags indentifying firearms inside your luggage instead of outside. Or don't bring a gun. You can't lose what you don't take with you. Or don't travel. It's a harsh world out there and risking losing your gun is part of the equation - choose wisely.
