Street art boomed in Bogotá during the 2000s, but interactions between artists and authorities were sporadic and contentious. When a police officer shot to death a young graffiti writer, a policy change was introduced. Leftist Mayor Gustavo Petro (2012–2015) opened a deliberative space to discuss the regulation of the artists’ use of public space. Such an experiment in collaborative governance led to the adoption of a decree. Yet in 2015, the left lost the municipal elections. For the new mayor, street art represented nothing but vandalism and the collaboration scheme of governance lost momentum.
