Less is difficult to say, but you'd imagine there'd be fewer massive death tolls like the las Vegas shooter as it would become even harder to get hold of automatics.
Stabbing and knives is obviously terrible, but no one stabs and kills a dozen people. Maybe the stats show there's more death by knives per person in the UK than by guns in the US. I doubt it but I'd take knives every time as I can run from a guy with knife.
Ok, I've looked 2017, 688 homicides in the UK for 66m people. That's all, including the terrorist attacks in London and Manchester. About 1 in 100,000 people.
2017 in the USA, over 14,000 killed in mass shootings (4+ killed) in population 325m. About one in 25,000 people.
It's not even close and the UK stats are EVERYTHING not just knives. Don't believe the hype. When you read "up 20%" stories you need to see the raw figures or its meaningless.
