"Mass shootings have become routine in the United States and speak to a society that relies on violence to feed the coffers of the merchants of death. Given the profits made by arms manufacturers, the defense industry, gun dealers and the lobbyists who represent them in Congress, it comes as no surprise that the culture of violence cannot be abstracted from either the culture of business or the corruption of politics. Violence runs through US society like an electric current offering instant pleasure from all cultural sources, whether it be the nightly news or a television series that glorifies serial killers."—Professor Henry A. Giroux

This latest mass shooting in Las Vegas that left more than 50 people dead and more than 500 injured is as obscure as they come: a 64-year-old retiree with no apparent criminal history, no military training, and no obvious axe to grind opens fire on a country music concert crowd from a hotel room 32 floors up using a semi-automatic gun that may have been rigged to fire up to 700 rounds a minute, then kills himself.

We're left with more questions than answers, none of them a flattering reflection of the nation's values, political priorities, or the manner in which the military-industrial complex continues to dominate, dictate and shape almost every aspect of our lives.

For starters, why do these mass shootings keep happening? Mass shootings have taken place at churches, in nightclubs, on college campuses, on military bases, in elementary schools, in government offices, and at concerts. This shooting is the deadliest to date.

What is it about America that makes violence our nation's calling card?

Is it because America is a gun culture (what professor Henry Giroux describes as "a culture soaked in blood – a culture that threatens everyone and extends from accidental deaths, suicides and domestic violence to mass shootings")?

Is it because guns are so readily available? After all, the U.S. is home to more firearms than adults. As The Atlantic reports, gun fetishism has become mainstream in recent decades due in large part to "gun porn in music, movies, and TV, [and] the combination of weapons marketing and violent videogames." (Curiously enough, the majority of gun-related deaths in the U.S. are suicides, not homicides.)

Is it because entertainment violence is the hottest selling ticket at the box office? As Giroux points out, "Popular culture not only trades in violence as entertainment, but also it delivers violence to a society addicted to a pleasure principle steeped in graphic and extreme images of human suffering, mayhem and torture."

Is it because the government continues to whet the nation's appetite for violence and war through paid propaganda programs (seeded throughout sports entertainment, Hollywood blockbusters and video games)—what professor Roger Stahl refers to as "militainment"—that glorify the military and serve as recruiting tools for America's expanding military empire?

Is it because Americans from a very young age are being groomed to enlist as foot soldiers—even virtual ones—in America's Army (coincidentally, that's also the name of a first person shooter video game produced by the military)? Explorer scouts are one of the most popular recruiting tools for the military and its civilian counterparts (law enforcement, Border Patrol, and the FBI).

Writing for The Atlantic, a former Explorer scout described the highlight of the program: monthly weekend maneuvers with the National Guard where scouts "got to fire live rounds from M16s, M60 machine guns, and M203 grenade launchers… we would have urban firefights (shooting blanks, of course) in Combat Town, a warren of concrete buildings designed for just that purpose. The exercise always devolved into a free-for-all, with all of us weekend warriors emptying clip after clip of blanks until we couldn't see past the end of our rifles for all the smoke in the air."

Is it because the United States is the number one consumer, exporter and perpetrator of violence and violent weapons in the world? Seriously, America spends more money on war than the combined military budgets of China, Russia, the United Kingdom, Japan, France, Saudi Arabia, India, Germany, Italy and Brazil. America polices the globe, with 800 military bases and troops stationed in 160 countries. Moreover, the war hawks have turned the American homeland into a quasi-battlefield with military gear, weapons and tactics. In turn, domestic police forces have become roving extensions of the military—a standing army.
