I think we are getting to a place where we are surrendering too many of our civil liberties to be protected. I don't think the police should be allowed to just walk up to anyone and ID them for no probable cause. The cop who ID'ed the people standing in protest is a great example of what the tip of the ice-berg looks like. Pretty soon, that crack the article talks about will widen. And when it does, our sons and daughters will not be able to walk to their church meetings, or their political meetings without some agent of the govt. being able to stop them and demand to see ID. And if you can't produce ID, they get to take you to jail. Freedoms are being eroded and we are loosing the appreciation of this, in our society.

I don't want the police tracking my movements because I might decide to drive a car with a suspended license or an unregistered license plate. I don't want the police monitoring me or my neighbors, just because I decided to stand outside the courthouse with a sign. This is wrong!
