Doesn’t quite work as well.
If people REALLY want to look to blame someone for inspiring things, they should look at the link between liberal horror writer Stephen King’s book (as Richard Bachman) “Rage.”
“Rage” concerns a loner who goes to school and kills the popular kids.
Several school shooters have either had the book in their possession or cited it in their manifestos.
