Let me get this straight:
The story I find goes that in 1782, Kamehameha, a very physically imposing nobleman in his 40's and ruler of Hawaii Island, but who had not yet conquered any other islands, was personally pillaging a village on Hawaii Island, and pursuing "commoners" who were attempting to escape the village, when the commoners fought back and nearly killed him with a canoe paddle.
Twelve years later these commoners were brought to Kamehameha, and it was apparently surprising that instead of executing them, he exonerated them on the grounds they were justified in their armed self-defense against a noble. And then he enacted the law of the splintered paddle, which said something along the lines of "if you harm somebody sleeping by the roadside you'll be killed".
How is this story invoked as an example of why citizens should be prohibited from having weapons for self-defense?
It's literally a story of a citizen using a weapon to defend their lives, to defend their lives from a murderous kleptocrat of all things, and then the official himself indicating that defending themselves was a totally justifiable thing for them to do at the time.
I completely fail to see how story doesn't illustrate the importance of having and using weapons in self-defense, from the state even, and how this story doesn't demonstrate that Kamehameha recognized a right to armed self defense, even from the state. What am I missing?
