> I would think that the right to life would take precedence
Well, let's do a thought experiment to test this. Which of these two rights takes precedence: (1) life (specifically in this case, the right to not be murdered) or (2) freedom of movement
That's an easy question, isn't it? (1) takes precedence. But how many 9's of protection are you willing to "purchase" at the expense of (2)? How much of (2) are you willing to give up in order to get a little more of (1)?
If we reduce (2) to 0 ...by locking every person in a padded cell, then we can achieve 99.99% protection of (1).
Presumably though, you don't like that idea. Presumably, you'll want to be let out of the padded cell, and get a bit of right (2) back. But giving you a bit of (2) back is going to cost someone their life! If we let you and others out of the padded cell, someone somewhere is going to get murdered.
What this thought experiment demonstrates is that the issue is not as simple as, "(1) takes precedence over (2)" - the thought experiment demonstrates that there is an amount of (2) that you will not spend in order to purchase a marginal increase in (1) - a situation where (2) actually takes precedence.
> Here in the UK, we have strict rules on gun ownership
And I totally respect that. Just to be clear though, "gun ownership" isn't really the issue. Gun ownership is a proxy for the actual right: self defense. You place a low value on the right to defend yourself and your family. Again, I totally respect that. You've "spent" that right to purchase lower gun crime. Have I mentioned how much I respect your personal decision?
As for me, I value the right to self defense above all. I've looked at the data, and I've realized that I'm much more likely to be stabbed or beaten to death than I am (well, was when I was in school) to be in a school shooting.
So to me, having actually looked at that data, it seems obvious that the right to self defense should take precedence. I think that my way of thinking is perfectly rational, and I think you're way of thinking is not ...but I totally respect your personal decision. I'm sure you also respect mine.
