The point isn’t that mass shooters use them or not, it’s that mass shooting are a VANISHINGLY TINY number of deaths a year. Space heater related fires kill something like 3 times the number of people who die in mass shootings each year, yet banning space heaters isn’t even an issue being discussed seriously
Why? Because space heater fires barely make the news, while mass shootings are front-page news for weeks.
Meanwhile, there are literally MILLIONS of recreational shooters, gun collectors and hunters buying various “assault rifle” variants for sporting and recreational reasons, without even a hint of issue.
But the “ban assault weapons” crowd wants to eliminate that activity and remove those millions (probably hundreds of millions) of dollars of commercial activity from the various state, local and Federal economies, just because a tiny handful of people got shot using one of those weapons.
As for the argument whether or not the government should have a monopoly on deadly force, it seems pretty obvious to me that the 2nd Amendment would have been worded differently if it was intended to ensure a government monopoly on power, and not to distribute it to the people.
At the time, there was a TINY standing army, and a whole lot of militias- typically local militias under the aegis of whatever state or territory they were part of. Think the Minutemen at Lexington/Concord- local guys with their own rifles who defended their settlements against hostile Indians, and when push came to shove, vs. the British Army. This remained the model up past the Civil War- most units were state regiments composed of companies from various localities.
The point of the 2nd Amendment was to ensure that the government couldn’t do away with the local militias by revoking the right to keep and bear arms. In other words, since the men provided their own weapons, a right to keep and bear them, kept the local militias in business. Why, you may ask, did they care about the local militias? Because having local militias meant that any sort of tyranny from a central government could be resisted by the people, much like they’d recently done vs. Britain.
In today’s world, you may argue that the National Guard fills that role, and in some senses, it does. But it fundamentally does NOT provide that armed check against central tyranny, being armed BY the central government, and tightly integrated into its military. Hence the thinking that an individual right to keep and bear arms provides for a potential armed resistance against central tyranny that the NG does not provide. It’s a little bit out there, I realize, but that’s the thinking. And before someone says “Well, civilians armed with AR-15s can’t fight the US Army”, I’ll point out that the Viet Cong and Iraqi insurgents did so quite effectively with very similar levels of technology.
The real question then, comes down to whether or not a certain level of insurance against tyrannical government is a better choice than some level of gun-related violence.
