This isn't a "whole new level" of ignorance. If you think so, then you probably don't understand how stupid a significant portion of the population is. There are people out there who think that Google, Facebook, so on, are actually on their computer. It makes complete sense that some people think a bomb looks like some caricature envisioned for the audience's benefit in a movie or TV show. Many people's entire lives revolve around motion picture entertainment of some sort.
