Are you assuming this individual is indeed a rightwinger, thus inherently extremist? Hell, they have not even caught the suspect yet.
At any rate, my point remains fact: Regardless IF the suspect is a rightwing extremist or NOT, the Barry media will run it/portray it as an act committed by a rightwing extremist. +1 for Napolitano and liberals via their recently released report on Rightwing Extremists.......!
So an extremist is taken out by an extremist, so what's the problem?
