Oh, for crying out loud. Who REALLY cares? The critics. In the scope of life, the Royal blood line is so freaking unimportant and so is there rules on how they want to be treated. Big deal, someone dared to walk in front of the freaking Queen. Did the heavens open up with lightening daggers and did the earth quake? NO.
People need to get over the entitlements the Royals have for themselves. My goodness, the world can survive perfectly well without any sector of it's population, including those with "Royal" blood. They eat with their mouths and crap out of their anus, just like the rest of us.
