I recently carried my L4, an X5 and a PM6 through LAX, Chicago, Quebec City and Toronto. They were all in my camera bag with several radios- HAM and marine. At all checkpoints my camera bag was thoroughly inspected, but the main thing they wanted to see was the camera lenses. They had to see through each one. Everything else got looked at, each compartment in the bag was checked, but no comment was made about the flashlights. I was rather disappointed, actually... --Bob
