Coming back from Aqaba in June, I ran into problems in Amman. Like most of you I presume, I normally hand carry both my computer and regulator, and my video system. I have never had a problem with this on any prior flight. In Amman, as I was going through the security screening, I got pulled aside for them to look at my hand luggage after going through the X-ray machine. No problem, that's normal and expected by now. However, I got an inspector who had no idea what I was carrying and would not allow me to carry either of those bags onto the plane. I fussed, and got him to bring his supervisor over - who agreed with him. They forced me to go back to check in and check the the two additional bags, and made me pay for the additional baggage. Of course, I had carefully gotten rid of all my JD's by now, and their VISA card reader was having computer problems at the time, so that was an additional aggravation. Additionally, since I always hand carry my video camera, there were no locks on my Pelican case. Needless to say, I was extremely unhappy about the entire process and worried if my gear was going to be pilfered before I got it back. As it turned out, everything arrived safely back home, but I was a mess for the entire flight back home. It really put a sour taste onto what had been a good trip.
Sorry, I just provided my PERSONAL subjective experience without any attempt to generalize it. And I'm very sorry to hear such a story from you - I can imagine the frustration...
