The Daily Cal has retracted this story, which originally reported that some Berkeley professors were claiming that the US may have carried out the Bali bombing.

The professors in question are justified to be concerned with such a false accusation on the part of the campus paper, but they should be even more concerned about the fact that it seemed like a perfectly credible story. They should be asking themselves why.

Dealing with that problem is going to require a lot more work than was getting a simple retraction.
