Police and jewelers must respond to all alarm signals promptly, and examination of only the ground floor doors and windows is not sufficient.
The roof, sidewalls and all possible points of entry must be examined, including through neighboring premises.
Rooftop burglars have come through the roof in mall locations as well as in other types of locations, and many jewelry stores have been entered by breaking through sidewalls after gaining entry to an adjacent store from the roof of that adjacent store.
