Seeing lots of claims that the increase in mass/school shootings is a myth. The problem is a profusion of definitions, which yield very different trends. The salient trait is not where shootings happen or how many deaths. It's the active-shooter profile. And those are increasing. 
You can tinker with the definitions to say that there is more than one mass shooting every day and everyone is about to die, or that there has been no increase at all and Sorry, the Facts Say You're Hysterical. These are both bogus. It's still rare, but definitely increasing.
I wish the @FBI would update their list continuously instead of every few years, because it's the most well-focused on the distinctive profile of the rampage shooting of any list out there (except perhaps for Mother Jones's) and could clear up misinfo if cited more often.
