Ive spent time in SA recently..
It really depends on where in SA you are talking about and where in the US you are talking about..
I shopped in VERY nice shops in Cape Town.. bought a couple of very nice luxury items.. and then WALKED 1.8 KM back to my hotel with those items in hand (a fairly large tube containing high end art work, and a bag clearly marked with the store logo containing very nice clothing items).. with my wife and my daughter.. and we all felt perfectly safe..
We self drove all over WC province while we were there.. from Cape Town down to Cape Point.. from Cape Town out to Stellenbosh, all around the city itself, etc.. never a problem.. and felt perfectly safe.. Also experienced ZERO load shedding.. we ate at fine dining establishments.. stayed in a 4 star western hotel (the westin).. etc... Frankly it was far nicer, and far safer than if we had attempted to do the same thing in Paris or London...
Johannesburg.. that is a completely different story..
But so are Dallas and Detroit.. There are parts of Detroit I wouldnt go to at 10PM on a Tuesday, any week of the year.. ESPECIALLY not with my wife and one of my children in tow..
I was a cop in the Memphis metro area for a bit more than a decade.. There are parts of that city I would not go to at 10PM on a Tuesday, any week of the year, even when I was a cop, with a badge in my pocket and a pistol on my hip at times I was off duty.. ESPECIALLY not with my wife and one of my children in tow..
Load shedding is just another word for "rolling brown outs".. something California residents deal with as a matter of routine these days (not to the extent of SA.. but we have them here as well unfortunately)..
New Orleans is the #8 city in the world for highest homicide rate.. The first South Africa city doesnt show up on the list until #12... Baltimore, Detroit, and Memphis come in at 17, 23, 25 respectively..
For overall violent crime proportional to population.. St. Louis and Detroit were ranked #1 and #2 in the world (for what its worth, Baghdad Iraq was #3, Kabul Afghanistan #4, Chicago #5, and Tijuana #6..
Im not claiming SA doesnt have real problems.. and that people traveling there shouldnt be careful and/or aware of whats going on around them..
But if folks believe shopping in Highland Park in Dallas or Bel Air in LA is indicative of the safety and security and stability of the US.. they need to open their eyes..
There are plenty of places, both rural and urban in SA that are FAR safer than parts of the US.. and there are plenty of places, both rural and urban in the US that are FAR safer than parts of SA..
Its all about where you specifically are, and what you are specifically doing, and how you are specifically behaving...
