CHRIS HAYES (ANCHOR): What's even more upsetting is how closely that shooting echoes what we saw last week in Missouri when a 16-year-old boy named Ralph Yarl accidentally went to the wrong address while trying to pick up his younger brothers. When Yarl rang the doorbell, authorities say he was shot twice through the door by a man who claims he thought his home was being broken into. Miraculously, Yarl survived the incident. There are two messages that come from conservatives that I think have brought us to this moment, where pulling into the wrong driveway or ringing the wrong doorbell gets you shot. The first, of course, is the message about guns. People are being told that guns are affirmatively good. Not only affirmatively good, they need to stockpile weapons for personal safety or to go to war against the government. The argument goes that everybody else is armed, so you better be armed too so that you can pull the trigger first. That's message one. The second message, and it connects to this, is a message about how terrifying it is out there, the constant stream of paranoia being fed to the American people by Fox. If you watch their programming, the idea that danger lurks behind every corner and the child that rang your doorbell is obviously there to murder you. This is the implicit, and sometimes explicit, message that plays constantly in right-wing circles across different kinds of media. At the same time, the Republican party pretends to decry gun crimes, only under the conditions that fit their narrative. The reality is the propaganda that they're spewing about guns and crime are going to make violence worse.
