TAMPA, Fla. -- A Tampa-area Wal-Mart manager who called sheriff's deputies to apprehend a black businessman over a check he found questionable was fired for using "poor judgment," but did not engage in racial profiling, the retail chain said Tuesday. An internal investigation of the Nov. 23 incident at a Wal-Mart supercenter in Brandon found that the manager, Mark Cornett, violated company procedures when he called the law on Reginald Pitts who presented a $13,600 check to pay for holiday gift cards for his company's employees, a Wal-Mart spokeswoman said.
