One of the students in my HLS criminal law class drew my (and his classmates') attention to this poll showing that a pretty solid majority (73%) of Americans now oppose banning handguns. What caused this? Did the Supreme Court's 2nd Amendment opinions (Heller and MacDonald) change norms? Or induce massive cognitive dissonance avoidance? Or maybe the NRA is behind the new consensus? Or maybe the public finally learned of the scientific consensus that there's no reliable evidence that concealed-carry laws have any impact on crime one way or the other? Is there a model here to follow for ending the culture war on climate change? Or maybe the climate change battle just made people forget this one?
