The DNA story is complete rubbish. McGrath has correctly pointed out that a quick comparison at the border cannot be done (for some time at least).

However, what the USA wants is those countries whose citizens do not need visa to enter the USA (EU countries, for instance) to include biometric data into their passport information. That could be facial data, fingerprints, iris data. These could (and would) easily be saved for later quick comparison each time someone with such a passport enters the USA. There are no plans whatsoever that the EU countries give all these data to the USA. The sampling is done only if someone enters the USA.

I think it is better to discuss the real plans than gross exaggerations.

By the way, all European passports at this time already contain biometric data like body length, colour of eyes and age. The disadvantage is that tens of thousands Europeans have the same combination of eye colour and body length and age. So, the idea is not to start including biometric data, the real idea is to start including biometric data that can be expected to identify one particular person for there would be most certainly noone else with the same pattern.

These are the plans worth discussing.
