Gradually, one violent event at a time, the bureaucracy and the politicians adopt a bunker mentality to protect themselves from the citizens, some of whom are violent and crazy. See below the design of a new government office building.
In the wake of the murders in Tucson we have congressmen (Peter King R-NY) calling for a ban on guns within 1,000 feet of any politician, and (Dan Burton, D-Indiana) proposing to wall off the visitors gallery of the House of Representatives with a bullet-proof/explosion proof transparent plastic barrier, among others.
Hey, guys and gals, we already have to go through metal detectors and surrender our pocket knives if we want to enter any government building. If the danger is so pervasive, then why isn’t the whole private sector similarly bunkered? A lot more civilians than politicians are murdered by crazy people every year. Next you’ll be proposing visiting facilities for citizens to communicate with politicians modeled after those in prisons? Why not?
The only thing they haven’t yet determined is which side of the glass the citizens should occupy.
