Some places are far safer than others. So safe that old folks live alone without any worry. As I indicated in my previous comment, it's the proliferation of drugs that threaten these places.
Your post reminds me of one of ADT guys that did an installation for me. He said that today people put up the best systems possible as a deterrent so that the thieves will rather go and steal next door than by their houses.
True, im not sure about it been just drugs alone or a major factor. They is tons of places in SA in which crime is a non-issue, but its a here-and-there..... And ofcourse you get scammers operating nationwide, I remember where I used to stay previously, in those days (only 15yrs ago) we could sleep with our doors unlocked and
open (PTA), you can do that now.
