 This approach had some appeal; after all, all states' definitions of "burglary" included the common-law definition of burglary — breaking and entering of a dwelling at night with the intent to commit a felony once inside.But the difficulty with this approach was that modern definitions have strayed far from the common-law definition.For instance, most states allow entry without "breaking," allow burglary to occur during the daytime, and require no felonious intent once inside.
