I've not seen any real correlation between a nation's gun laws and a reduction of murder rates or violent crime in general. The authorities know this, too. It's not about crime. That's a red herring. My considered opinion. Hope I'm not being too political here.

The politicians Keen to be seen to be doing something, even if it's not effective. media jump on the bandwagon when there is an incident urging 'action'.
Look at recent crossbow armed intruder at Windsor , journalist showed how easy it was to purchase legally " killer cross bows" . Something Petti Patel , Home Secretary is urgently looking at crossbow legislation.
same as @belchy being fairly new to firearms and yes those initial stats are old, I found those stats and thoughts really interesting and lots to think about before giving my t'penny worth for sure
