Where's The Logic?

Unexploded car bombs in England and a threat in Glasgow that the US was "warned about two weeks ago" means that all security in US airports has to be increased?

Where is the logic?

I think they just enjoy jacking with us. These activities actually increase feelings of insecurity -- and I think they are intended to.

I wouldn't travel by air this week for anything. Not because of threats, however; but because of unnecessary "security" that does not make anyone more secure.
