The reason why she would make it up is to avoid a felony conviction.
And she did elbow him pretty good in the eye. Even the defense didn't argue it didn't happen. There's a video of it. Clearly the photos you show doesn't show the actual incident. And to be honest the cop looks pretty calm in the photos. She looks like a crazy weirdo like all the other Occupy Walls Street folk were.
Now, I certainly don't think she deserves 7 years in jail or a felony charge for that matter. I was just commenting on the boob grab. Because who doesn't like talking about a boob grab.
