Next time someone declares that your modern modular rifle system is a "weapon of war" that has no place in civilian hands, remind them of this: the internet as we know it is the evolutionary offspring of the "web" that connected national computer centers to improve survivability in the event of a nuclear event taking out some of the nodes. "The US Department of Defense awarded contracts as early as the 1960s, including for the development of the ARPANET project." (cite)
The web itself -- the INTERNET! -- was designed for war. What possible use could it serve in uncontrolled civilian hands?
Besides, the old dead white guys that wrote the U. S. Constitution never foresaw telegraphs and ARPANETs and internets and computers and tablets and iPhones... any more than they foresaw lever action carbines and turnbolt rifles and AR-15s.
(Yeah, but those guys were rich racists or whatever. Or something. Good night.)
