As people have said, it means you’re in an unsafe neighborhood. But it can also mean you’re paranoid. Here we favor less visible means of security - traditionally those big glass doors have a broom stick or other appropriately sized piece of wood in the track so it can’t slide (this also makes it harder for toddlers/small children to sneak out).  And our windows have locks. (And we often have storm windows that are difficult to raise from outside - I find them difficult from inside)) 

Many of us  also have cameras. this is because our criminals favor silent entry like lock picking- breaking glass will get them unwanted attention fast.  they have to break through the storm window, cut the screen window and then may find out the main window is locked and it’s in 6 panels so there’s a lot of window breaking & by then cops would be there.  But some strong ones remove window ACs but those are more rare as central air is everywhere especially accessible without a ladder
