'still have' doesn't begin to describe it. shootings doubled in the first 5 years after the 97 ban and have kept rising since.
According to this
Gun Crime Report, there was a peak around 2003 and figures have been in decline since (fig 3). The variation seems to depend on ease of importing.
but the british are STILL convinced bans work and every time a shooting happens in the US they scoff at the US gun laws.
I'm not going to scoff, and I don't approve of the bans we instituted after Dunblane (nor similar tabloid-led legislation over the last 10 years). However, even in 2002 we had only 0.15 gun homicides per 100,000 people, and the USA had 3.98 (fig 6). So pro-rata, the USA has 26 times as many gun-killings as the UK. For whatever reason I think it is working better here than in America. Only around 0.2% of our recorded crime involves guns. It's a different culture. In general when the public encounter the police here, neither side expects the other to be armed.
