"The cards say that the ride is peaceful, that they exercise their right to remain silent, that they don't consent to a search and don't give up any rights. The card also has the name of a lawyer to contact."
Those rights are for american citizens, not those who don't respect the borders, laws, and culture of our nation.
The ride may be peaceful, albiet smelly, but yesterday at the Chgo. rally they were getting all riled up and loud!
