I think the biggest problem with all of this debate is the data being used is flawed.. or at least biased to how certain groups want to perceive it. the BS of mass shootings defined as 3 or more fatalities... or this data set over here is defined as 4 or more not including the shooter... blah blah. BS
If the study doesn't include non fatalities, only considers public spaces... and doesn't include drug or gang related violence, which none of them seem to do.... then the data is tainted when being used to talk about shootings and gun violence in America. Take away private property shootings, where most gang related and drug shootings occur, take away gang drive-by and turf wars and only counting the ones with higher fatalities, or fatalities at all, paints a completely different picture. Include it all and your "Since 1982, 54% of mass shootings, (in which 3 or more fatalities were reported), were committed by white men" data point would go up in smoke, big time. It would probably be closer to 95% of all shooters are black if you considered all of the data points. Even the Stanford definition, which I think does a better job than mother jones, includes shootings even if they are non necessarily fatal, yet they still exclude anything gang, drug or organized crime related shootings.
"The definition of mass shooting used for the Stanford database is 3 or more shooting victims (not necessarily fatalities), not including the shooter. The shooting must not be identifiably gang, drug, or organized crime related."
Why do they do this ... because most folks are desensitized to black drug/gang related violence, especially when the info or data comes from places like Chicago. It doesn't help their narrative so therefore is not included. Throw in non-fatal, drug/gang related firearm shootings/statistics... and the % for scary black "assault rifles" being used in shootings, wouldn't even be enough to register on the pie charts. But that wouldn't help the so called "assault weapon" case now would it.
Every time I see a newscast or read an article that starts talking about mass shooting statistics from one source or another it makes me want to vomit, because I know whats to follow is going to be a load of horse shit.
