THIS is what firearms looked like when the 2nd Amendment was written ...

[Confusious]

153. I am realistic enough to know that we cannot merely presume original intent,

Sorry, but we presume original intent all the time.

On the other hand, original intent is usually bullshit. We don't live in a world were it takes months to get to Europe, the only means being a boat, horses aren't the primary means of transportation, communication long distance isn't done by letter, etc, etc, etc

My prediction:

I don't think it matters how many or who, massacres are just something that we're going to put up with. The politicians just ain't got the balls. People will forget the victims until the next massacre. Just hope you're not in the wrong place at the wrong time. CC ain't gonna save the hobby warriors, nor will it save the victims.

The gun lobby and gun nuts will blame everything but guns, and around and around we go. Spending hundreds of billions to protect people from an industry that's only worth 2 billion. (As your engineering company is doing)

Of course, I don't have the luxury of forgetting anymore. I'm reminded every time I get into the shower and wash the 45 scar, one on the front of my leg and one on the back, where someone who shouldn't have had a gun had one and tried to kill me with it last year.
