I urge you to oppose S. 1757, Senator Cornyn's so-called "Building America's Trust Act". Because the Department of Homeland Security (DHS) interprets its authority to act at the border as a much broader authority, giving itself broad power to act domestically anywhere within one hundred miles of the United States' land borders, this bill would carry the effect of expanding the means, scope and intensity of domestic surveillance within thousands of square miles of US territory, exposing US citizens and residents to warrantless invasions of privacy. I have seen such invasive searches first-hand. When I and a native American friend were driving outside El Paso Texas, wholly within the United States, we were profiled as smugglers and subjected to an invasive search of our possessions. When I was on a public bus Oceanside, California, the bus was flagged down by Border Patrol agents, every passenger who looked 'Mexican' was asked to show identification and one passenger was taken away. It's a stunning violation of the Fourth Amendment but yes, these injustices continue to happen in the United States, DHS's newspeak definition of the 'border' and doublethink interpretation of the Bill of Rights allows them to continue, and Senator Cornyn's bill would aggravate this already unjust status quo.
