On the suggestion of "Al" I have updated Just One Question. It's now:

Can you demonstrate just one time, one place, throughout all of human history, where the average person was made safer by restricting their access to handheld weapons?

The previous wording was awkward and a bit ambiguous. This is much better. I did tweak it just slightly from Al's suggestion but still he deserves the credit for recognizing the poor wording and the appropriate correction. Thank you.

Update: Ry, in the comments, suggested even further improvements. I removed still another word after taking his suggestion. It's now:

Can you demonstrate one time or place, throughout all history, where the average person was made safer by restricting access to handheld weapons?
