There have been several horrific events which have brought out the worst of humanity to take advantage of people gathered to either worship or enjoy themselves. Most, if not all, if my memory serves me, were perpetrated in designated safe zones. This is the hallmark of people who are predators.
The person attacking anyone with deadly intent is an angry and aggressive psychopath with no sense of the moral dimension of their crime. Their internal logic is different from yours.
Those thwarted in some criminal enterprise for profit, who use firearms to get gain, may recognize the error of their ways and stop. Those driven by compulsion won’t stop. You need a good tool to save you. Whether that tool is a firearm which you’ve been trained to use, or a baseball bat, the result needs to be the same. That psychopath needs to be stopped or the carnage will continue.
The second amendment was a recognition of human behavior in all its forms, both good and bad. It’s not there because, oh by the way, we may want to hunt, go to sporting events, or collect interesting mechanisms. It was written as an inherent right of every free person to defend themselves or their property.
Just as important as it is to be able to speak freely, gather together in common purpose, prevent unjustifiable search, arrest & property seizure, worship how we may choose; self-protection is absolutely fundamental to a free society. Without it, the other civil liberties can’t be guaranteed.
Eventually, without a second amendment, a greater form of tyranny emerges, and there’s no way to readily restore prior conditions. To keep pace with these real and constant threats, the law abiding citizen must be able to continue to legally possess and use the latest in weapons technology.
It’s not about sports, militias, parades, or historic relics of the past. It’s about each one of us being able to defend & protect against any aggressor, no matter their size, shape, or societal status with weaponry capable of matching that challenge.
Societies protect themselves, and so too should any free individual person, unless we accept our fate to the whims of criminals, and the providential timing of a benevolent government appointed employee.
Freedom comes at a price purchased by the observant, able to work, and willing to sacrifice for it.
