It seems he has officially been charged with possession of child porn. Though no arrest warrant has been issued.
My humble opinion is no. This is sounding more and more like his ex had a threesome, the boys spread it around to friends to brag. Mo being one of them one of those who was sent the video. She got caught and now to save embarrassment is claiming assault. The video should easily be able to tell if she was willing or not.
He tried to get back with her, she said she is not interested, he gets pissed. Sends the video and calls her a hoe.
This was a horribly stupid decision on his part. However, I would venture to guess if you go on any 14- 17 males phones you would find some sort of "child porn" on a high percentage of them. Mo shouldn't be labeled a sex offender for the rest of his life, nor have to suffer the rest of his life for a stupid teenage decision.
