The only 'mass shooting' was the Philly one. Intellectually stunted and politically blinded morons are trying to change the definition by lumping in gang bangers doing drive bys and shooting up house parties. If you Individually dig through the gunviolencearchive.org sources, the overwhelming majority of them have an African American teenager with a handgun set out to settle a personal vendetta; yet somehow that scenario is - by gunviolence.orgs own statistical criteria - categorized the same exact way as a deranged psychopath with an AR-15 randomly shooting up a mall (which even once is way too fucking common, but not as statistically prominent as the site is trying to mislead the public to believe).
Why can't it be both? Especially when guns are so interwoven into the culture.
So it's not a mass shooting if the person is black and the crime is personal? What led you to come with that criteria? I tend to think "A mass shooting is a violent crime in which an attacker kills or injures multiple individuals simultaneously using a firearm." is a pretty fair definition. You know "mass" as in several individuals involved and "shooting" as in a firearm was involved. Keep it up with the mental gymnastics though.
