What are the comparative populations??

I would not go for a midnight walk in JHBG,London,Moscow, or Central Park NY either.
I could easily be a victim of a mugging in any of those Cities, wether i would survive is less likely in Jhbg than London.
Mbali raised the point about Midrand, which encompasses places such as Ivory Park and Thembisa but also quiet suburb's such as the ones i mentioned totalling around 20,000 Homes.
Mbali also called into doubt the veracity of the press in reporting crime.
and made out as if the whole thing is a storm in a teacup and IF you take care,you will be ok.
Thats Bull.
Now,if you really want to compare levels of violent crime, i'm happy to do so, kindly remove vehicular and pedestrian fatalities from the UK figures, they are easy to find.
Secondly,SA has a low rate of petty crime as if the SAPS cannot solve and convict 91% of the murders and 88% of the rapes, does anyone even report petty crime?( Source SA Law Commision on Conviction Rates)
In fact, I have beeen in a SAPS ploice Station reporting the abduction and rape of a 21 year old employee of ours, when it was suggested to her that she might as well forget it, they would never catch them,
I did report it, immediately,to the Station Commander, zero action, friend, and that was a rape.

I stopped reporting anything that's too much hassle years ago, am sure there's many more like me.

But thats not the issue, you can be a victim of crime anywhere, you can also spend 40 years in SA and never experience any crime, but, if you do happen to cross someones path and you experience contact crime in SA, its likely to be life changing, or ending.

You are trying to minimise the crime problem in SA.
