US borders continue to be lawless places. Not because there's more criminal activity there, but because the Constitution that protects us away from borders (and international airports, etc.) barely applies at all within 100 miles of them.

The First Circuit Court of Appeals is the latest appeals court to decide borders and constitutional protections don't mix. A lawsuit over warrantless, suspicionless device searches has been rejected, with the court finding in favor of the government.
