Looking at the number of people killed in just this incident below, it struck me that we probably lose as many people in separate shootings in a single day in the United States, pretty much every day. I couldn't find any data for gun deaths PER DAY in a quick check of available information; but with 50 states, DC, and assorted territories, whatever the number is, it adds up. But in smaller, more distributed numbers, with more people committing the violence, it is easier for us to become immune to feeling shock or horror.

The shooting at Forum Roller World took place just after 7 p.m. when an argument during a party got out of hand and someone pulled a weapon and opened fire, Grand Prairie police told the NBC station.
In all, 10 people were shot, six of them fatally, including the gunman, NBCDFW.com reported.
The gunman died of an apparently self-inflicted gunshot wound, police said. The condition, identities and ages of the survivors were not immediately known.
