Since 9/11, the US Federal "security" apparatus have claimed the right to intrude into the personal lives of US citizens and lawful permanent residents on the grounds of the necessity posed by the radical Islamic threat emanating from the Middle East, as well as from home grown "terrorists" of all stripes.
Obviously, the principle means of entry for any serious terrorists organization would be through the US' famously undefended border with Mexico.
And yet, not a single "terrorist incident" has been traced to any group or individual exploiting this most vulnerable vector.
Could this strange anomaly be due to US Federal policy effectively endorsing the open southern border?
