There are, in my opinion, two types of run out.
There is the type which is due to fantastic fielding, which South Africa seem to specialise in: see this AB Devillers effort, this flying leap from Jonty Rhodes, or similar athleticism from Herschelle Gibbs for proof. Even their domestic cricket seems to be full of such occurrences.
The other type of run out is where the blame lies entirely at the feet of one or both of the batsmen involved. South Africa are no strangers to this type, either. Perhaps my favourite example, though, is this double play. The first batsmen run out isn’t even holding a bat as he tries to make his ground.
