We live in a very security-conscious society - unfortunately, the reality is that we have a really high crime rate. So for us, it's not unusual to see security measures like this (though quite honestly, I think they're trying to keep out scavenging baboons rather than criminals here). I've seen a few pictures on other city blogs of spikes or broken glass on top of walls - how common are things like this where you live? Do you lock your doors at night? Do you have a burglar alarm system in your home?
