DMV bans ex-cop's Osama tag.

Fools.

The federal government may have a $25 million reward for fugitive terrorist Osama bin Laden, but a retired city cop says the Department of Motor Vehicles has banned his "GETOSAMA" vanity license plates as offensive.

Arno Herwerth, 42, a retired NYPD sergeant from Hauppauge, in Suffolk County, told The Post he's flabbergasted by the DMV's kibosh, terming the agency's move as "unpatriotic" and political correctness run amok.
