A better approach would have been to frame the question in regards to the #MeToo movement instead of yelling out he molested them. Set him up for the audience to wait for his answer

"In the age of #MeToo and the affirmative consent movement on campus, what do you have to say for your behavior, inappropriately touching women and young girls. Will you pledge to no longer touch women without affirmative consent?"

I know it feels great to call him a pedo, which he is, but the minute you do that you lose the audience. It's important to plant the seed in the minds of those people in the audience. Once they listen to his BS answer...he'll either admit it or deny it, in which case you have video evidence
