There is no public evidence that TSA has caught any person actually carrying out or imminently attempting an Islamist terrorist attack at an airport checkpoint in the last five years, and experts generally note that TSA's screening programs have not credibly documented a single terrorist caught at the checkpoint in their entire history. Now the door opens for the TSA to collect your DNA. ? Patrick Wood, Editor.

New strict customs laws have gone into effect, allowing government officials to request tourists' DNA in some cases. The new biometric data collection started on December 26, just ahead of the new year.

The new rule targets non-citizens entering or leaving the US, according to government documents seen by Reuters. Travelers will now be subjected to facial recognition photos at the airport to help match them against existing records. Those facial recognition pictures will be stored for up to 75 years, according to the documents.
