"Hundreds of thousands of travelers cross US borders every day. And none of them—save the precious few with diplomatic immunity—have any right to privacy," Vice reports.
"This is a familiar routine for most travelers: A CBP official checks your documents, glances between you and your passport photo, and perhaps asks whether you’re travelling to the United States for business or pleasure."
"If you are referred for a secondary inspection, your right to privacy is essentially moot. Either a CBP officer or an Immigration and Customs Enforcement (ICE) special agent will likely question you and may inspect your possessions. This can mean anything from a quick look through your bags to copying and detaining your electronic devices—it’s up to the agent and his or her supervisor, not due process."
