Your history is wrong, and the killing power of your average citizen hasn't gone up significantly since the end of the 1920s. Look up the Bath school bombing in 1927-near double the casualties of the current tragedy.

Your interpretation is interesting, though.

Edit--Okay, say, the roaring 20s with the Thompson.

The 2nd amendment: 1791. The first practical automatic repeat firing weapons didn't show up until almost 100 years later and they still required a crew to operate. There was a touch of progress in that first 100 years.

I'm going to go ahead and make the weak point that bombings, poisonings, and sabotage are a slightly different animal than purpose build firearms and would likely be treated differently in the law. There is a huge element of luck to those attacks.

The crux of it is, that rampages last 5 to 10 minutes. This is probably going to be true whether the first responders are armed citizens or police. We're going to have to decide how many people we're going to allow a private citizen the capability of killing in that time. We're going to have to very explicitly choose or technology will choose "a whole damn lot" for us by default.

I'm thinking your point just indicates that we should have started addressing this long about the time Swing was King.
