Accidents happen. Unfortunately, some come with legal consequences. Frequently, we are contacted by individuals who carry a firearm into TSA screening checkpoints at airports in their carry-on bag. Not one of the people who have called us, has ever knowingly done this. On the other hand, we have received calls about this type of incident far too many times.
In one such case, a husband and wife arrived at the airport. He grabbed the two heavy suitcases, she grabbed her purse and his backpack. When they went through the security screening, he placed the two carry-on suitcases on the conveyor belt and she placed her purse and his backpack onto it. The husband never even realized that his wife was carrying his backpack. He had not intended to take the backpack on the trip. It had still been in the car from the last time he went to the range and had his gun and ammunition in it. Only when the TSA agents asked whose bag it was, did he realize she had grabbed it from the car.
