I'm watching the NRA news conference and Wayne LaPierre is speaking about what his organization thinks about the Newtown shooting:
(1) In summary, politicians are responsible for school shootings because they create gun free zones and advertise them.
It's a good tactic because politicians have the popularity of dirt. However, it's a rather flawed view of the world. By the NRA's line of reasoning, politicians are responsible for drunk driving because they create and enforce drunk driving laws.
