Why copy editors are useful

They correct embarrassing mistakes like this one in The Progress Report e-mail:

The AP has obtained the FBI files on playwright Arthur Miller, a "longtime liberal who opposed the Vietnam War" and "supported civil rights." (In 1956, Miller famously refused to name names before Eugene McCarthy's House Un-American Activities Committee.) One FBI report said Miller's "religious" wedding ceremony was a "cover up" since he was a "cultural front man" for the secular Communist Party.

Ouch. They've corrected it at Think Progress.
