Sorry, my post wasn't actually aiming at you, my point was to separate developed and western countries from countries with different issues.
I didn't even want to be critical about South America at all - but where public safety is concerned, the region requires extra precaution and should be not treated in the same sense as the OP was going to somewhere like Florida.
Thanks, that is very true... In Sao Paulo I would put my iPad in my pack in the trunk when taking a taxi for example, which i would have never thought about in the other countries I was in...
