If she wanted to go to a party and have consensual sex, that isn’t what happened anyway (according to her).
Following your dumb analogy it would be like saying on camera you want to get into a fight before a party, and then someone sucker punching you at the party and kicking you on the ground.
I wouldn’t say, “well he said he wanted to fight.”
DAs only bring a case to trial if it’s a slam dunk. People should know this by now. I’m not saying he is personally guilty either, I’m just saying you can’t say she’s a liar. We just don’t know.
