zimmerman traffic stop*George Zimmerman has become a national celebrity for all the wrong reasons.

However, after his acquittal in the shooting death of young Trayvon Martin, Zimmerman has wisely kept himself out of the spotlight.

In Texas, a cop is under investigation for snapping Zimmerman’s photo after pulling him over for speeding, as we reported.

Law enforcement sources tell TMZ, the officer who pulled Zimmerman over for speeding on Sunday is currently under investigation after dash cam footage revealed he took an iPhone picture during the stop … at least that’s the way it sounds.

The site says you can plainly hear the telltale sound in the video — followed by the “unlock” sound and typing iPhone keys.

It’s unclear what photo the officer snapped — or if he sent it to anyone — but if he took a pic of Zimmerman’s driver’s license for personal use … he could be in serious doo doo.
