Bundy was a self-serving jerk and it sounds like Stayner is as well. It is not uncommon for a heinous murderer to play the "victim" and blame his conduct on someone or something else.
Finally, the Meese Commission study on pornography that you impicitly referred to in an earlier post never concluded that there is a connection between pornography and violent crime.
It's interesting that you mention that. Bundy was interviewed by a Christian conservative where he said he was fueled by pornography. After that Liberals became inflamed that it was a conservative conspiracy to quash pornography ...
If so, wouldn't it be wise for Feldman to introduce some kind of expert, to say this? For absent such testimony, the juror is free, to make the connection for himself, justified or not.
