In my Katrina column yesterday I mentioned that I hadn't seen any first-hand confirmations of the widely reported helicopter-shootings that suspended aid operations a week ago. I still haven't seen any such eyewitness accounts (which of course doesn't mean there weren't any), but yesterday a New Orleans man was arrested by the feds for shooting at a helicopter.

And The New York Times has a report about other reasons for helicopter-reticence in those first days.
