And tbf most people with any sense would hear the guy out and abide by his demands. Not jump them with zero fearAnd how often does this happen in the UK?
One of the results of things like the UK gun laws is that pretty much any use of even an imitation gun in a crime results on the police throwing resources at it.
It's also interesting that the circumstances around it are still being investigated, because that sort of crime is so unusual that I suspect there is a lot more than random guy goes up to someone's door with a shotgun in broad daylight.
