This tweet put me in mind of a project I’m planning on doing at some point, and posting in this forum.
In the spirit of trying to make an important point without "well actually"ing a grieving person (which is something we pro-2A types so often do, myself included), I think it’s important to note that 45 rounds per minute is just not that much. I’m pretty sure I could do this very easily and at a leisurely pace with no practice using a double-barreled coach gun like this one:
I think it would be useful to do some rate-of-fire exercises with old-school guns and compile the info, here, just as way to give people some perspective on what real-world rates of fire are and how little they matter in a mass shooting scenario.
Rate of fire matters a great deal when someone is shooting back. But active shooters are walking around and shooting unarmed people who are trying to shelter in place, and in these scenarios they always fire in short bursts and then have relatively long pauses.
To take Parkland as another example, there’s the famous “6 minutes” that Gonzalez does in her speech. If you were going not by rate of fire by buy the number of targets shot at center mass (as a proxy for fatalities), again, you could use the above linked coach gun to get a much higher body count than 8 dead in that amount of time if nobody is shooting back and everyone is sheltering in place.
I think this would be most usefully demonstrated with a video, although it would take a lot of effort to ensure that the tone is respectful and that the discussion around it is productive. It would basically involve simulating a number of different mass shootings on a range, which is likely to provoke serious backlash (and maybe even a visit from law enforcement) no matter how it’s handled… which is probably why nobody has done it.
