"These 800,000 people are the public face of Olympic security.
Behind the scenes, an unknowable number of people are monitoring
all those cameras and microphones; hacking computers and stealing
secrets; monitoring web sites and reading e-mail; listening to
phone calls and tracking the movements of suspicious people.
"Of course, the terrorist threat to the Olympics is real. But
most of the security effort is aimed at snuffing out protest or
criticism of the government."
