You have a point. First one is that the porn was out there on the internet. What does that say about our country, or it's citizens as a whole?
Now the question about whether freepers get off on it is in a scale to our society. Get off on, I doubt. Curious? probably.
.........Still not proof of murder.
"Get off on" is a term I wouldn't use in this case or hopefully any other topic of discussion. It is a perverse term that is often used by women in anger to describe a sexual activity.
Anger, sex and a woman scorned are as dangerous as TNT.
