Is it a violation of anyone's civil rights to go door to door after a homicide is commited in the neighborhood? It's the same thing. Police are invesigating according to a demographic.
While I find idiotic lawmaking like the "Patriot Act thoroughly repulsive, I find nothing wrong or unconstitutional about questioning people who fall into the same demographics as the terrorists for information that may be helpful. What the hell is wrong with asking people to voluntarily give information about potential atrocities?
A violation of a civil or human right means that someone is harmed. Can anyone tell me who is harmed by this?
