Most people have no sense of our history and our revolt from England. The was one thing that got our colonists pants in a bunch and that was illegal searches and seizures and quartering troops in peoples homes without asking. We made laws to forbid that but most people who are frightened will always sacrifice their freedom but more importantly others freedom.
I don't care if they ask and illegals but it's our citizens who look like they don't belong here that will be hassled.
