For the data errors in the one published paper by Aneja, Donohue, and Zhang that claims to find a bad effect from right-to-carry laws on aggravated assaults see this paper.

In addition, Aneja, Donohue, and Zhang have retracted their original claim that the my research could not be replicated. Their argument was that Aneja, Donohue, and Zhang could not replicate the replication work done by the National Research Council that had replicated my research. In an Erratum note published in October 2012 they concede: "Subsequent to the publication of this article, members of the NRC panel demonstrated to the authors that the results in question were replicable if the authors used the data and statistical models described in Chapter 6 of the NRC (2004) report."
