Some movie-plot attacks actually happen:
They never touched the floor—that would have set off an alarm.
They didn’t appear on store security cameras. They cut a hole in the roof and came in at a spot where the cameras were obscured by advertising banners.
And they left with some $26,000 in laptop computers, departing the same way they came in—down a 3-inch gas pipe that runs from the roof to the ground outside the store.
