I just don't see either happening. Here is why, the 2 boys who were in the video, secretly filmed it, and they dispersed the video to half the school have already been to court and as far as I understood were not convicted of a Felony( distribution of child porn, same thing MO is charged with) They were given probation. So I find it very hard to believe MO, who had nothing to do with it, and 3 years later will get convicted.
Here is the things you are not taking into account.
1 -The 2 boys who originally filmed the encounter were minors.
2 - The school administration told all of the students, who had a copy of the video, to delete the video. Washington appears to not have deleted his copy.
3 - The 2 boys weren't charged with the revenge porn law, which, in my opinion, could be validated by the fact that Washington appears to have kept the video even after he was told to delete it.
Again, I am not saying that Washington will be or should be over punished. I am just saying that I don't believe comparing the 2 boys situation to Washington's situation is your best argument for why Washington shouldn't be punished.
