The New York Times' public editor caused an online storm overnight when he asked readers whether the paper should become a "truth vigilante". Putting aside the loaded headline, Arthur Brisbane raised whether Times reporters should challenge facts asserted by people they are covering. He gave two examples -- the first about Supreme Court justice Clarence Thomas claiming to have "misunderstood" his financial disclosure obligations, the second about Mitt Romney's contention that Barack Obama has "apologised for America", which he has never done.

Brisbane's point was that op-ed columnists have the freedom to challenge such assertions, and that the Times has been running a sidebar to presidential nomination stories that fact-checks claims by candidates, but such analysis was not currently part of the straight reportage of the Times, and he wanted to know whether it should be.
