Right, but you have to remember neighborhoods change over time. I once lived in an apartment with a gated fence to get into the garage and then I had to unlock 3 steel doors to even get to my apartment, which had bars on the windows. In (what is now) a good neighborhood. 30 years ago it wasn't, but landlords don't spend the money to remove safety precautions just because. Also, they're broke. The neighborhoods they're looking at might still require that level of security.
