It seems the computer security course I used to teach was an
inadvertent terrorist training camp.

"A flyer designed by the FBI and the Department of Justice to
promote suspicious activity reporting in internet cafes lists basic
tools used for online privacy as potential signs of terrorist
activity. The document, part of a program called "Communities
Against Terrorism", lists the use of "anonymizers, portals, or
other means to shield IP address" as a sign that a person could be
engaged in or supporting terrorist activity. The use of encryption
is also listed as a suspicious activity along with steganography,
the practice of using "software to hide encrypted data in digital
photos" or other media. In fact, the flyer recommends that anyone
"overly concerned about privacy" or attempting to "shield the
screen from view of others" should be considered suspicious and
potentially engaged in terrorist activities."
