Are you referring to the "" string on the boarding pass?  That
indicated that you were going to be searched by the boarding gate TSA
people whether they were going to decide to search you or not (they
still picked up "random" people without the search string on their
boarding passess).

Both JFK and SFO have stopped gate searches.  Searches at security are
still decided by the TSA personnel there (they don't get to see your
boarding pass).

LHR still has gate searches, and the mix of people they were searching
looked fairly random.  I don't know if any of them had been flagged by
the computers, or if the gate security personnel had picked them out.
I wasn't searched, either going through security or at the gate, but
when I tried going from the gate area back into the duty-free area
they were pretty thorough (but exceedingly polite).

Re: NSA being used to influence UN votes on Iraq

2003-03-02 Thread John Ioannidis
Why is this even newsworthy?  It's the NSA's responsibility to provide
sigint and comint.  Furthermore, if the delegates are not US citizens,
and at least one end of the communication is outside the US, they are
not even breaking any laws in doing so.

If the delegations can't be bothered to protect their own
communications, it's their tough luck if they get intercepted.
