It’s not unusual for the department to send a van to transport all the criminals Ross arrests at this Walmart. The call log on the store stretches 126 pages, documenting more than 5,000 trips over the past five years. Last year police were called to the store and three other Tulsa Walmarts just under 2,000 times. By comparison, they were called to the city’s four Target stores about 300 times. Most of the calls to the northeast Supercenter were for shoplifting, but there’s no shortage of more serious crimes, including five armed robberies so far this year, a murder suspect who killed himself with a gunshot to the head in the parking lot last year, and, in 2014, a group of men who got into a parking lot shootout that killed one and seriously injured two others
