Background: My colleague just told me that he reckons Donald Trump's presidency is most likely to end in assassination. My first thought was: "Why not put money on it then?"; my second thought was "Would that be legal?".
From the bookmaker's point of view, taking such a bet would be stupid: if a person stands to win £100,000 from Trump being assassinated, it would give them motivation to pay someone up to that figure to carry out the killing. Further than that, I wonder whether giving someone motivation to kill someone could legally count as inciting someone to murder, which is illegal. Hence why I wonder whether it would be legal for a bookmaker to take such a bet.
As I'm from the UK, I'm mainly interested from the UK legal perspective, but any other international perspective is welcome.
