DH has several. As does DFIL. I suspect at least one of my DC will when they grow up. I could name at least half a dozen other people who do. As per PP we live very rurally and regularly hear shots (likely organised shoots, occasionally farmers). Where we are, a high percentage of our neighbours would own guns.
Personally I've never even touched one and have no idea where the keys to any of the cabinets are kept.
I am an absolute advocate of extremely strict gun laws and there are a lot of hoops to jump through to own them (including proving why they are required). Your license goes as far as to stipulate the number of bullets you can own at one time. They are also immediately confiscated if you are ever in any trouble with the police (at the point of accusation).
The events in the US are beyond horrific. I wish they'd wake up and get over their bloody 'rights'. What about the rights of those poor babies?
The laws in the UK were changed massively after our single (at least in my lifetime) school shooting. And it worked.
