Still frustrated..

This week in class we brought up the subject about the couple who was getting charged because they had child pornography, even though it was about them selves. To this moment I am still frustrated about this subject because it makes absolutely no sense whatsoever. I think if the individual is putting them selves in that situation because they are in a relationship with the other person it is obvious they knew exactly what they were doing. They weren't doing it against their will. They decided to send each other that content in their own privacy so why should someone come and tell them its "wrong"? I mean come on its the 21st century...
