It isn't that hard to cut a hole in the vinyl siding then through the sheathing and drywall to get in.

Good point. In fact several years ago an inmate at our county jail escaped by cutting a hole through the sheetrock and stucco with a butter knife.

What do you mean it isn't that hard?

Cut vinyl siding.
Cut sheathing (dense glass or plywood)
Remove insulation and possibly utilities
Cut and punch in another 16" section of drywall

Then I suppose you could just walk right in, assuming there is no furniture on the wall and no one has noticed your little construction project in the middle of the night.
