The only answer here is to let everyone on the plane carry as many guns as they can, as long as they fit under the seat or in the overhead compartment. I mean really, suppose one of these FFDO boys goes bonkers, or as we say in the industry, “has a JetBlue moment “. Now he or she has a firearm and starts spraying the passengers. (I mean customers.) I’d sure feel better if I had two Glocks, a J-frame and a mini 14 to shoot back.
