My SA colleague is really upset by this. She says that level of paranoia is very common where he lived and seems convinced it was an accident.
Though of course some may find it pretty hard to believe that someone who’s your national hero could do something like this deliberately, so it’s very easy to see how the ‘accidental’ thing has come about regardless of evidence. There’s even talk of a Valentine’s surprise gone wrong.
Whatever happened, it’s very, very sad.
