Here and here are some interesting articles on the story of a Baltimore couple arrested for "trespassing" on a public street. Here are a list of more links.
The first thing that jumps out at me, from seeing the picture of hte couple in the first link, is that I would really, really like to see what race the cops that arrested them were. Maybe I am dead wrong, but I have a strange feeling that I know what the answer is. If I am correct, I'll comment more.
That is all.
