Is it a scandal that Parliametary security was so lax as to allow Jonathan May-Bowles to pie Rup Murdoch?

When I saw the way he walked in I was blown away that only Rupert's wife reacted, flooring that puffy, pathetically balding creepo. Where were all those police? If a Jonathan May-Bowles can get into a Parliamentary committee hearing with a pie, then a Mohammedan terrorist can blow up Parliament, and a right-wing skinhead fanatic who thinks he is Guy Fawkes II can do the same. Where on earth is Britain's vaunted security system and what does this mean for the royal security around the royuals?
