Gun Control & RKBA

Not an argument. Quite frankly, it wasn't relevant to the discussion. If you are there, you are the first responder. The police are minutes or hours away, that is reality.
As you saw from the video, assuming you took time to watch it, armed citizens mitigated the carnage. That isn't me, the NRA, France's UNPACT, or Canada's NFA, that is INTERPOL, not the band. Let's use another example. Orlando. Most who died, bled to death from their wounds. If OPD didn't stand around with their fingers up their asses for three hours, or if someone thought of rushing the fucking asshole when the set the rifle down to reload magazines, many of those people would have been saved.
No, as the Westgate Mall example showed, simply historical fact. The police and military showed up hours later. As the report shows, more would have died. Besides, self defense is a fundamental human right. In fact, it is a natural right afforded to all species.

What evidence is there that open carriers, assuming there was more than one, impeded the police response? I know there were pundits and politicians making the claim, but politicians and pundits tend to be stupid, intellectually lazy, and almost always full of shit. My understanding is that the one simply walked up to a cop and surrendered to say that "I'm not part of that". Open carrying rifles, or pistols for that matter, is stupid as shit in an urban area for a number of reasons, but impeding the cops isn't one of them. Especially political protests, like children, openly displayed weapons of any kind should not be there.

The sentence is incoherant, but if I understand it correctly, people will spontaneously direct their fire at the source of the attack. You are relying on the speculation of comedians and pundits who, quite frankly, don't have a fucking clue what they are talking about.

Mostly because our system is set up, our country was founded Enlightenment concept of, government is a necessary evil that must be limited to those that are necessary for a state to function. This antiauthoritarianism expands to a lot of things. Want to sell a lot of something? Start a PR campaign against it. Doesn't matter what it is. Most of the "controversy" surrounding the video game Grand Theft Auto came from the company's PR arm.

Speaking of Red Dawn, which as nothing to do with being in a shopping mall or a concert during a terrorist attack, the reference is made by people who don't know shit about asymmetrical warfare. It was a stupid movie for a couple of reasons, but not for the reasons you might think. The one Democratic congress person I admire most, Tom Lantos, lived it after he escaped from a concentration camp. Granted it was Nazis in Hungary instead of Communists in Colorado, but you get the idea. There are people in the world who live the real thing.
