Do you think talking about Death or killing Human Life must be about politics? I know it's a bit subjective!
Where else should it go... chit chat? A bit of a heavy subject for just chit chat... And I doubt a "death" section would go down well on ET
The Las Vegas nutcase and the others conclusively prove that there are some that enjoy killing people. Perhaps they start on animals and can be spotted earlier ? Wire them up to electro-shock therapy for a weekly session until they change their twisted minds imho.
