There is no need for poker to be involved when it comes to people stupid and callous enough to commit armed robbery and murder (for non-life changing amounts of money, no less).
In my area, for example, there was a murder of a farmer some years ago by bunch of young people, led by older ringleader.
These kids got the idea into their head that the farmer was rich, and kept a lot of cash in his house.
This gang was young and dumb enough to think that a few thousand dollars was a lot of cash. As it turned out, the farmer didn’t even have a few hundred on him.
They broke in, there was a struggle, and one of them ended up stabbing the farmer to death.
They found no more cash than you’d find in the pocket of your average convenience store patron. In truth the farmer was barely making enough to feed himself and his wife and pay their property taxes. Anyone with half a brain would’ve known that farms in our area typically carry a lot of debt, are hardly flush with cash.
That was the problem: not having any brains or sense. But politicians will always assume that poker was the problem in the rare cases game gets held up.
PS: One of the news reports that I read noted that the victim was not the host, and described it as a “targeted killing.” which is quite different, if true, then a botched robbery.
