"Up to 80% of gun homicides in this country are gang related, either black on black (55%), or Hispanic on Hispanic, and occur in the inner cities."
That's the point. If there weren't so many guns on the street, there would be fewer gun homicides.
"Deaths from mass shootings are such a small percentage of the total, they're almost irrelevant." They're not irrelevant to the friends and family of the 59 people killed and 500+ wounded in Las Vegas.
