It is a bizarre subject matter for a widely read newspaper but I think there are plenty of terrorists already among us for me to fret too much about them learning many new TTPs based on the media. Not to mention I am sure most of them have seen the various Insurgent sniper training powerpoints that are circulating on their sites. The PROVOS were doing this in Northern Ireland years ago and its being done overseas now. It doesn't take too much research to read up on the Sparrow Teams or to watch some Hollywood movies to come up with simple ideas that would have great impact.
