The suggestion that the shooting of Rep. Gabrielle Giffords Saturday might have been influenced by political 'vitriol' seems less likely as more becomes known about suspect Jared Loughner.
In the halls of Congress, the Arizona shooting has prompted calls to tone down violent rhetoric. But it will take more than reformed lawmakers to change politics' tough-talking culture.
Early reports suggest that the philosophies of shooting suspect Jared Loughner are tangled and largely incoherent – ranging from nihilism to 'lucid dreaming.' So far, there does not appear to be clear link to talk radio or hyperpartisanship, though that could change.
