Nope, not buying that. She claims to have been beaten, kicked and strangled, if nothing else she would require medical assistance after being abused like that. Even if she didn't admit to being raped initially, the majority of women would seek medical attention especially during a stranger rape.
Secondly her and/or her friend placed a 911 call claiming to have been taunted with racist slurs. If she had the mental capacity to do that, then drive/ride to a grocery she could easily have called for help via 911.
And one more thing. Let's say things happened as she claimed. She was taken into the bathroom and raped by 3 men. Now, she has a friend with her, a female friend. Both are obviously outnumbered, what do you think the chances are that men, hell bent on rape, are only going to rape one of the women....
What about the reports of her injuries in the hospital and the rape kit? Are we to discount all of that as well when we don't even know the whole story?
