Walls

I lived for three years in a country where there were checkpoints and forbidden zones. Where, if you went around the traffic circle next to a certain government building more than once, you would automatically be arrested. At the time, that country was a military dictatorship. Now it's a democracy. I don't know if the checkpoints and forbidden zones are still there; I haven't been there for over 15 years.

But we seem to have plenty of them here.

Interesting thought, isn't it?

If this moves you to write your congressfolk, there is an alert link here.
