Seconded, his videos are mind bending. Why is the milk gone is my personal favorite

Yeaah! I stumbled upon his channel not very long ago and was so hooked I just watched like 15 videos in a row .^.

He is a rapist and abuser. I encourage you to look at the journalism investigating his case and the inadequate police response to it.
