Ebbie, it may look "curiously like the USA" until you look at actual numbers. A BBC report says that in 2019 there were 32 homicides in the UK involving guns (4% of all homicides). The USA had 14,400 (74%). Other figures suggest that was a good year for the US. Even allowing for the larger population, that's a big difference.

Americans are 25 times more likely to die from gun homicide than people in other wealthy countries.

I take Bill D's point that the US has painted itself into a corner. But to outsiders, it looks crazy. Other countries have managed the transition from a state where people routinely carried weapons to a state of law and order whether they don't. It's not the Wild West any more.
