I've only come onto this thread today, but as a Capetonian I can tell you that Cape Town is still an amazing place. Yes, we have a violent past and present, and yes there are inequalities that are visible at every turn. But, what many tourists (and locals for that matter) fail to understand is that wealth and privilege protect you from most of the dangers that afflict the lives of South Africans (yes, the Mount Nelson attack was a rare case). As a tourist, you will have access to your own private vehicle, a comfortable place to rest your head, lavish meals, etc, etc. The vast majority of crimes and all of the gang violence is happening in the townships, that you will never, ever see. Come on down.
