the only robberies that get 'attribution' are cases where the criminals get caught. i.e. low hanging fruit and thus these statistics skew to opportunistic events.
however, unplanned opportunistic crime makes for good promotional sales of window bars and strong locks. just like safes with electronic keypads.
very few such devices will stop a premeditated theft... and what is the rate of recovery for stolen goods in most jurisdictions?
False, opportunity theft is the most common form.
Better doors/windows/locks help the most, and help against both opportunistic and targeted.
