The NSA and FBI would be unhappy to know that this email contains
no information for Echelon about bombings killing people.
It may contain information about Information Security, Hacking, PGP,
So you guys can go Blowfish at the next HOPE conference.
This is my own part of the Information Warfare Stop reading my mail.
If this is not directed to you via a mail list you are not entitled to read
it.
