Gatwick airport measures

To Whom it May Concern

I want to express my strong complaint against the measures undertaken by the British airport-Gatwick, last week. On Monday the 16th of November at 20.45pm, I was travelling back to Dublin from London, (flight FR 117 with Ryanair). At the last official check of my documents in Gatwick airport, I had to be exposed to an unjustifiable taking of my picture, as well as each one of the people waiting behind me in the queue. I asked on what grounds each one's picture is taken, which is the exact law that can back up such a procedure, and the only answer I got is: 'This is the rule, so that internal flight passengers don't mix with international ones'. I still try to fathom the meaning of the phrase, the logic behind it, and honestly, I cannot find it. I cannot understand the reason : no law was presented on my lawful request in support of my civil rights, and my choice not to have my picture taken hasn't been respected, not even considered as a possibility.

Moreover, just before entering the plane, there was a scanning of everybody's tickets before we entered the plane. With every scanning, each passenger's previously shot picture appeared on the screen. I am wondering which British law actually supports such procedure, and I really wish, as part of my civil rights, to be informed about it in writing.
