Legos Out The Door

I was at the mall doing Christmas shopping when someone opened the nearby emergency exit, setting off an alarm. The people closest to the door knew immediately what had happened: a thief had fled through the door carrying a box of Legos with him. I suppose my superhero instincts should have kicked in - the thief was struggling with the box while running only a short distance away - but I just couldn't summon enough outrage to pursue him. Legos are expensive, but so is medical care. Who knows how it would have turned out?
