Bogotá has become a mecca for graffiti artists since Diego Felipe Becerra was gunned down by police in 2011 for spray-painting a Felix the Cat image on the walls of an underpass. The city was incensed by the shooting and the cops’ subsequent attempts to portray Becerra as a suspected armed robber. There were protests and the eventual arrest of two police officers. Today, Bogotanos are proud of this art form. We took an organized tour this afternoon of breathtaking murals on the sides of buildings depicting mystical landscapes, trippy psychic scenes (think 1960s album covers), and protest art about the plight of Colombia’s victims of the 60-year-old conflict.
