Are you in the UK? Being new, I don't know. But for those who are in the UK, this should not be a surprise at all. They've always had their share of random killings with guns, knives, bats, swords.
I was going to post the same thing for the most part. Although we do have some UK members, Bob is not one of them.
In England and the surrounding environs, random violence for the hell of it is the primary national pastime. It surpassed cricket and boiling random things and calling it cuisine a long time ago.
Only the Home Office cooking the books and counting only "murders" that are actually convicted as "murders" vs. plead lesser to manslaughter, or... never solved at all allows them to foist the fabrication that the UK is safer than the US on everyone. A true accounting shows them to be even with the US despite draconian gun control, if not actually a smidge higher.
