Our collective memory has some very powerful images. Photo editing software enables us to manipulate them and use them to communicate a message. "Learn to anticipate" says the ad below with a set of shortened WTC towers and planes happily flying over it. Maybe the ad was meant to be funny. Maybe its intention was to shock people and trigger a discussion of a controversial subject (What Benetton tried to do in the 1990s). A "fail" on both accounts. Be careful with charged visual concepts.
