In the first pic in the upper left, that is a pencil next to the "harmless little circuit board with harmless wires" and "little bags".

The plastic thing laying on top of the armrest, is a garage door opener, about the size of a pack of regular size cigarettes, which gives a perspective to the realatively SMALL size of this IED, compared to your "harmless" cartoon "advertisement".
So as long as someone takes the plastic explosive, and shapes it into a cartoon figure with a few LED "Brite-Lites" that is "hip" and recognizable to people like you,( which CAN be done )you would IMEDIATELY think it's "OK" because it's just a "harmless advertisement".........
