.@fred_guttenberg, u all might actually read the underlying research before commenting on the data sources.
The data used was described in detail here
papers.ssrn.com/sol3/papers.cf… as well as in MGLC (Univ of Chicago Press).
As to my research being discredited,

The post also shows the cases from 1998 through 2015, which has a similar percent as the entire period. All data provided.

If you think that the @nytimes is missing mass public shootings,
1) Identify the cases
2) show that they don't fit the definition.
If you think that the @nytimes is missing cases, as our research notes, given that few states had right-to-carry laws, the true rate of attacks in gun-free zones is likely even higher than we note. But if you don't like the NYT list, use our data for the later period.
