It's the "new normal" start of the fall campaign season -- the heightened terror alert:
All snark aside, the government is right on this one -- certainly the Olympics have been a target for terrorism (in 1972 and again in 1996 -- remember Atlanta?) and so have the first year of new presidents, in 1993 and again in 2001. What's annoying is the way that the Bush administration politicized terror alerts leading up to the 2004 election. That makes it harder for people to take new terror alerts seriously -- even if there might be something to it.
