Yes you’re right, it’s not technically a law.
I’m the odd duck in thinking that almost any country would easily find 3/4 of its state/provincial legislature votes needed to approve a repeal of an amendment similar to the 2nd amendment. I am more than baffled by the logic behind keeping it around.
Even the most progressive segments of the US aren’t generally in favor of getting rid of it entirely.
The list of countries with similarly permissive gun laws is basically one-hand’s worth, and none of them are G20 countries. Basically the United States is in the company of Yemen and almost nobody else.

Anyway, sorry, this is horribly off-topic.
