Tourists regularly get mugged in this place.
I went on a daytrip to the Falls back in 1992 and forgot I had a camera around my neck [a very ordinary point and shoot but it had the photos of the Falls on it]. I was leaving the very next day.
A man snatched the camera and the strap eventually broke even though I had a jolly good go at fighting him and there was a second person trying to get my little backpack.
The hotel manager was very useful and the Police know all of the local crooks. They actually managed to get my camera back but I had to pay a reward of G$800. Yeah, its a corrupt little place.
