Katt Williams Slapping Target Employee Caught On Video

There's no audio, so we can't tell what the argument is about -- but by the looks of the employee's body language before the wallop (placing his hand on his chest) the guy wasn't looking for a fight.

Then out of nowhere Katt winds up and slaps him in the face -- at which point the employee pulls out his phone and, according to an eye witness, he calls police.
