The Lafayette theatre shooting was the 204th mass shooting in the US this year – 204 days into 2015

There were 18 mass shootings in April, 39 in May, 41 in June, and 34 so far in July

The headlines all start to sound the same after a while. Seven people shot inside Louisville nightclub. Four men shot in Suffolk early Sunday morning. Two dead, two hospitalized in Brice Street shooting.

The shootings happen so often, the circumstances become so familiar, that we tune them out. One dead, five injured in west Columbus shooting. Four shot in grocery store ambush. One dead, four injured in Stockton shooting.

Every now and then a particularly heinous crime makes us pause and reflect. Nine dead in shooting at black church in Charleston. Four marines, one sailor killed in attacks on Chattanooga military facilities. Gunman opens fire on Louisiana movie theatre.

The Mass Shooting Tracker, a crowd-sourced project of the anti-gun folks at the Guns Are Cool subreddit, lists 203 mass shooting events so far in 2015. Add in the shooting at a Louisiana movie theatre on Thursday night and you get 204. Incidentally, Thursday was the 204th day of the year.

The Mass Shooting Tracker is different from other shooting databases in that it uses a broader definition of mass shooting. “The old FBI definition of Mass Murder (not even the most recent one) is four or more people murdered in one event,” the site's creators explain. “It is only logical that a Mass Shooting is four or more people shot in one event.”

These shootings have become so common that they typically don't even make national news. Do you remember the four people shot in Cincinnati earlier this month? How about the seven in Cleveland, or the nine in Fort Wayne? Unless you live in these areas, you probably didn't even hear about them.

This year there were 18 mass shootings in April, 39 in May, 41 in June, and 34 so far in July — and the month isn't over yet. The theatre shooting was Louisiana's 8th this year. There have been 10 in Ohio, 14 in California and 16 in New York.

Will anything change? Probably not. The Charleston shooting did produce a fruitful national conversation — not on guns, but on the symbolism of the Confederate flag, which the shooter adopted as a banner of his racist beliefs. It took 150 years and a national tragedy for the country to reach something like a consensus on the meaning of a battle flag.

“Those who live in America, or visit it, might do best to regard [mass shootings] the way one regards air pollution in China: an endemic local health hazard which, for deep-rooted cultural, social, economic and political reasons, the country is incapable of addressing,” The Economist wrote in response to the Charleston massacre. “This may, however, be a bit unfair. China seems to be making progress on pollution.”
