Submission + - Swimming Terrorists! (ishackingyou.com)

Apparently, they now have a way, using sonar and some advanced software techniques and lots of expensive equipment, to track potential underwater swimming terrorists in our ports! The article features what they call an "acoustic tripwire" which can analyze ambient noise at a choke-point port entrance, and detect suspicious activity and track it!
This is all really interesting but — why wouldn't Johnny Jihad simply jump into the water inside one of these choke-points? Personally — I think we have bigger problems than terrorists with submersible bombs swimming into our ports to blow themselves up."
