Unfortunately, I have a photographic memory. Thus, after 9-11, I was required to register myself. I am now a Registered Photographic Offender and I must report to Homeland Security whenever I move, and must gain advance permission before I approach any government building or entity.
When I travel I am subjected to a brain scan to insure that I have not memorized any critical security detail. Luckily for me I have an ISO 25 brain (I'm a little slow), so these scans do not fog my memory.
