BBC News is running this press release from the University College London: http://news.bbc.co.uk/1/hi/technology/6044310.stm
“Electronically tagging passengers at airports could help the fight against terrorism, scientists have said.”
But the only explanation of how this will actually help the “fight against terrorism” is
“the tags could aid security by allowing airports to track the movement patterns of passengers deemed to be suspicious and prevent them from entering restricted areas.”
Which seems to roughly translate to
Step 1: Tag passengers electronically so you can track their movements
Step 2: ???
Step 3: Security!!
Oh, I missed step 0
Step 0: Get big fat grant from the government and impress your fellow professors
The BBC obviously don’t ask any pertinent questions.
