Now most are due to homicides and, finally (c) The Brazilian Landless Movement (MST, Movimento dos Sem-Terra) started the year of 2004 invading more private properties, including productive ones, changing its previous strategy. The author examines these facts and compares them to other similar South American countries, observing that Brazil does not have a shining scenario concerning respect to property rights.
