Why not link to another story you've all probably read already? Economist Tyler Cowen at the Volokh Conspiracy briefly explores the potential costs and benefits of establishing a market for betting on when terrorists will strike. Basically, Tyler thinks that the main danger of such a market would be an excess of accurate information that might lead to panic.
Tyler is quickly becoming one of my favorite Conspirators, and he has written some excellent posts on macroeconomics as well.
More by Glenn Reynolds of course. I try not to read Instapundit until I'm done with all my other sites, because otherwise I'll have a hard time thinking of something to write about that hasn't already been done.
