Hi Jim. In my opinion the grates on windows, especially in older homes, do not necessarily indicate that there is a crime problem. Many years ago it was fashionable to put the grates on windows, crime or not. I personally think they are a fire hazard and would never place them on my own home, and I would probably remove them if they were on a home I might purchase. Lynn, who posted earlier, is correct when she says you should check with the city PD to determine crime stats in any given area. Crime can happen anywhere; it does not discriminate by price range, demographic or any other kind of variable. If someone wants to get into your property badly enough, they'll get in - no matter what kind of security you have. Many police departments nationwide will tell you that some of the very best security measures are lighting and barking dogs. If an area is brightly lit a criminal will usually pass it by - motion sensitive outdoor lighting is great for this. And a barking dog draws attention criminals don't want - they need to be unseen to do their dirty work.
