Sounds like horses and barn doors
You have wonder what Holder, the US A-G has for brains.
The idea is stop people stealing the goodies, rather than prosecuting them, which implies a criminal charge. And since the US has domain only after it's own courts, They don't usually give prior notice, either, which is the idea behind the sealed indictment.
Of course, the US hasn't time for the niceties of law, ask the Canadians how many times US law enforcement has come over the border - even kidnapping people and taking them back to the US (only to have to release them)..
As we all too well know, now, there are many governments only to happy to let their citizens be 'renditioned', including Britain under bLIAR, and most likely would happen again under Mad May, the Home Secretary.
Of course, the US government has full access to Sabre and Galileo reservation systems (Amadeus servers are in Europe) so they can sit back there in Washington seeing potential victims. Ask CHOY, Hon-Tim and Nick Leeson, both of whom were detained by the use of Res systems.
Do you think Dot.Com is free to travel, irrespective of any restrictions imposed upon him? There are very few places he can travel without hitting a US-friendly country. Scrub Australia and HongKong. Maybe China? Land movements are the safest for miscreants - they can be done illegally without passports.
What would be far more appropriate is for the US to actually implement some security so their goodies are protected.
