This is a view from my balcony of an apartment block next door. The metal railings are a common addition to many homes here. Sure, it makes it a much harder jobs for thieves to break in, but it also makes the place look like a prison. You may ask why they do not use a burglar alarm instead. Well, I am fairly confident it is because the sound of an alarm wouldn't begin to pierce through the blare of horns, fireworks, construction work, and neglected car and bike alarms.
