No, Al, the FBI report does not only include cases where the shooter was committing some other crime. Did you read the report? Go read it again and come back. They quite clearly say what their criteria are: Someone with the intent to kill multiple people, where at least three people die, and they exclude accidents and gang-related things. They absolutely do not specify it has to be part of some other crime. I'm not sure why they wouldn't have included the shooting in the theatre, but do note their study covers the years of (off the top of my head) something like 2000-2010, and does not itself cover the most recent events such as that one. Perhaps they've done a treatment of recent shootings elsewhere, but the document I mention, whose purpose was to track levels of active shooters over a decade (and which does note a slight increase by a few a year), stops several years ago in its data.
And yes, shootingtracker.com isn't completely nonfunctional and I never said it was. But some of its features are incomplete, making it look slapdash, like someone's home project. I will note again that this sad-looking site is the single source for ALL claims about mass shootings in the hundreds per year, cited all over the internet and elsewhere. By contrast, when I did a search for mass shootings articles, ALL other articles (no exception, not one) mention around 20 for 2015, including sources such as the NYT and other MSM publications, and some articles including the NYT even refute outright the silly "363" number cited all over the place (and sourced from that one site, a massive echo chamber propaganda machine). ZERO independent sources came to the same conclusion as that one website, and when pouring through the data on that website back when I looked into it I concluded to my satisfaction that the intent of whomever compiled it was to accumulate the maximum number of incidents possible in order to beef up the number. The author had an agenda, that being to show how had things are in America. Do you want to place bets on whether this person is a Republican or a Democrat?
Al, the GOP does lie frequently about things, and wills say anything to further their agendas. I hope you won't be caught in the same trap and stoop to this level. shootingtracker.com is a partisan farce meant to trick the public.
