The era of personal privacy is finished.

At this intermediate point, the US INS is not equipped to identify every in-migrant, whether tourist or long-term illegal, or something else.

Over time technology will allow complete identification of every person. Comings and goings, etc.

Regardless of personal views of privacy, its absence is a fact of the future. At some point complete identification will be implemented. At that time, for those of you still willing to travel and who meet the criteria, I would predict an easy passage into the US or France. As for getting past the guards at Sheremetevo, who knows? That was never truly about identification in the first place.
