I didn't know about this since I've been away from news since yesterday, so I read up a bit on it just now.
I'll reserve my judgment on the shooting until more is known about the gunman, but the scary thing is that, as shocking as this is, it's not far-fetched for something like this to happen as a result of the ridiculous and hateful propaganda that keeps coming out of a bunch of greedy cowards and hypocrites on the right.
