<human>: Condense the text into a few key points

My girlfriend was traveling through the London International airpot earlier this day. She calls me when she reaches her gate and tells me that she was just forced to have a body scan done. She said that she had made it through the metal detector with no problems, and was getting her stuff from the belt when one of the TSA (are they called TSA in England?) guys came up to her and told her she was randomly selected for a full body scan. She asked if that indeed was a 'thing' and whether or not there were other possibilities available. He responded saying that he was sorry but there really was nothing he could do, and that she did indeed have to comply with regulations.

After the scan was taken and she had gathered her belongings, a group of fellow Americans came over to her and told her that the TSA (I still don't know if this is the right term, but I'll use it again anyway) agent, during her scan, had gone over to the monitoring station and fist-pumped (or pounded so to say) the other guy at the monitor. This obviously was a bit embarassing for my girlfriend, and when she told me about the entire situation, I was a bit more than annoyed. 

Now I'm not trying to come off as arrogant or braggardly... but my girlfriend is 19 years old and hot as hell. I'm a bit protective, within reason, I don't stifle her in any way but I don't appreciate other men oggling her. Is this entire situation even legally acceptable? I could have sworn that 1) the tests were supposed to be actually random and 2) the images were supposed to be only viewed by one person, not even on site? 

Maybe I'm overreacting. Not having been there there's nothing I can do, and the rational part of my mind tells me to drop it. But in the back of my mind, in those darker depths where I don't have as much room to reason, I am still bothered by this... Am I overreacting? Opinions?
