There are 6 BILLION internet users. So 1 in 100,000 internet users have viewed these rape videos. Oh wait, less than that, that's for the whole site. Oh wait, less than that, that's hits, not unique visitors. Oh wait, only half of that 6 billion are men, more or less. Oh wait, women view porn, too. Etc.
This takes it from something that statistically is a concern for my small city to something that statistically has a single dangerous individual in my city, at most.
We perhaps shouldn't make special units to deal with this where I live, but should maybe have awareness courses for law enforcement and healthcare professionals to help identify potential victims. Larger cities may want to take a different approach.
