If you watch alot of TV crime shows you see alot of killings for made up reasons. However, this kind of stuff sticks with some unstable people and may cause them to go off and do the same thing for whatever reason that suits them. Then again the Wisconsin shooting may have been inspired by a terrorist(s) as was the Ft. Hood killings. We will never get to the bottom with the truth about this killing with BO in office.
I do believe the television shows plant seeds that bear fruit. It’s a very low percentage though, and I question if the weak minded might not find another reason to go postal.
I also think about rat studies where over saturation of a population base at some point starts to cause members of the test ‘society’ to become detached from normal behavior and act out in bazaar manors. Is that part of what we’re seeing.
If we wanted to reduce these abnormal behaviors, I think some simply common sense tactics could achieve it in short order. Thankfully for some, we’ve got the psychologists to make sure that doesn’t happen.
