All registered Democrats, as was Chris Dorner. There is a common denominator you don't hear in the news. If they were all Tea Party or Republicans, it would be the cause of the problem and conservatives would be labeled mentally ill with a special section in the DSM-V. However, since the shooters all seem to be registered Democrats, and since these Democrats are the ones pushing gun control, I say gun control should only apply to them. Oh, and as a disclaimer, I am not a Republican. I am just pointing out inconvenient things the Soros....eh, state run....I mean, uh.. Main Stream Media...missed...overlooked...IGNORED.
