Sure she has..
On March 14th at about 1:30 AM: she told Ofc. Shelton that she saw the AV walking alone down Buchanan St. when a bunch of white guys ran out of the house and starting yelling bad words at her, so she picked her up and brought her to safety. She told him that was the first time they met.
On March 22nd at about 2:30 PM: she told Ofc. Hinman that she arrived at the 610 Buchanan house at about 11:00 PM and chit chatted with the boys till about 11:30 PM when the AV arrived. She said they walked to the back porch where they talked about the dance. She told him that was the first time they met.
Darby, has Roberts told the police Mangum was raped and also told them she wasn't raped? Has she told them they were always together except for less than 5 minutes and also told them they were apart longer than 5 minutes or long enough for what Mangum said happened (in whichever of Mangum's stories the prosecution is going with) to have happened? Has she told them Mangum's story was a crock and then told them it wasn't? Did she tell them Mangum wanted to go back inside to make more money and then recant that? That's what I'm talking about - not when they first met or who drove whom where afterwards, but what happened at the house in relation to Mangum's claims.
Roberts lied to the cops about picking Mangum up because she didn't want to go into the dance thing, who she worked for, and all that. She wanted to avoid giving them reason to think anything wrong or bad or fishy about her because she wanted to avoid them doing a warrant check. Being an exotic dancer and working out of an escort service are usually a signal that you have a record of some sort. She lied in the 911 call because she was pissed off at the boys. Neither of those events have anything to do with whether or not Mangum was raped. Those two events are only peripherally related and have nothing to do with the heart of the case. It's not complicated at all.
Roberts has not given conflicting statements to the cops with respect to any facts she's aware of surrounding Mangum's claim of being raped. If you find one, let me know.
