The shooter is a schizophrenic person who took the ideals of the Tea Party to extreme due to his mental illness. That does not, however, excuse the Tea Party from being aligned with the same kind of zeal that's found with an Islamic extremist - say a Taliban fighter. If I was a politician I too would be fearful against Tea Party retributions much in the same way abortion clinic doctors are afraid of getting bombed by zealot pro-lifers.
