It doesn't happen with just shopping malls or gallerias. This kind of incident also happens in homes where the garage faces the street. It is not called smash and grab but grab and run. Just a different phrase. If you have the habit of leaving your garage door wide open, there is a crowd that runs this kind of activity wherein a guy will just enter your garage and grab anything they can and run or drive off.
Quite a while back, perhaps over a year ago, there was this guy (sometimes it is a different face) going around our street checking out (casing) houses here...These guys pretend to sell something. Or just walking our street. Someone from our neighbourhood reported to the police his tools stolen where minutes ago he was using. Happens in daylight hours. Friendly police check out our street for days, caught the guys. We never see them again. Anyway, almost all of us here are armed, apart from two jerks down the road from us.
