Well, here’s some good news (theoretically) — from Benjamin J Newman and Todd K Harman:

“Drawing upon multiple data sources on mass public shootings paired with large-N survey data, it demonstrates that increased proximity to a mass shooting is associated with heightened public support for stricter gun control. Importantly, the results show that this effect does not vary by partisanship, but does vary as a function of salience-related event factors, such as repetition, magnitude and recency”

Soooo, statistically … as more and more mass shootings occur, public support for gun control may reach a point where all the political lobbyists in the world won’t be able to counteract public demands. Sad way to go about it, though.
