This Fall, the Duke Law Journal held a symposium Heller at Ten: A Symposium on From Theory to Doctrine. All of the articles are, at least partially, responses to an article Eric Ruben and Joseph Blocher that analyzed data for all post-Heller cases, from 2008 until early 2016. From Theory to Doctrine: An Empirical Analysis of the Right to Keep and Bear Arms After Heller, 67 Duke L.J. 1433 (2018). Examining data from 1,153 cases, Ruben and Blocher presented a wealth of interesting findings. For example: pro se plaintiffs rarely succeed; Second Amendment claims have a better chance of success claims in civil cases than in criminal ones; and lower courts rarely use historical sources (only 29 from before 1791, and only 42 from 1791-1868).
