If those who continually watch porn are seeing women get raped and the rapper get away with it, it creates a false sense of authority. Since these people see others get away with crimes, perhaps they feel like they can get away with it as well. The audience is also seeing the pleasure that the rapper is getting from raping this woman, so in the long run perhaps men rape women because they have seen others get away with it with extreme pleasure.
It is just like if children watch someone do something dangerous on TV, they are now exposed to something that they never would have thought of themselves and so they want to try it. There are people that have never been exposed to rape and they watch a porno and they now are exposed to this horrible crime, but they see the pleasure involved so they decided to try it themselves.
This may not be true for all criminals but I sure am willing to bet that there is at least one rapist out there who decided to do it because he saw it in a pornography.
