[Cicero]

I always used to carry a penknife in my pocket. My guess is that these folks just forgot to leave their pocketknives at home.

Yes, I always carry a Victorinox Tinker (the one with slotted and phillips screwdrivers) in my pocket. Usually, I put it in my checked baggage for a flight. One time I forgot and donated it to the next Security Guard Flea Market fund. They put it in a drawer with SEVERAL HUNDRED pocket knives in it. Not a bad daily take from careless people.
