RIO DE JANEIRO , Brazil ( CNN ) -- Antiviolence protesters stretched out 16,000 coconuts on Brazil 's world-famous Copacabana beach Saturday , each one representing a victim of urban violence . Protesters used dummies to represent victims of violence on Brazil 's Copacabana beach this week . Activists from ONG Rio de Paz led a protest march Saturday morning that included residents and tourists who usually can be found on the beach on weekends . The protesters strung up a sign on the sand that said `` Shame '' in Spanish , Portuguese , English and French . They finished with a minute of silence for the victims of violence . Rio de Paz said the coconuts represent victims of violence , homicides , dead police officers and those who have been shot in gunfights between authorities and gangs of narcotics traffickers . The figure itself was obtained from official information from the Rio de Janeiro governmental Institute of Public Security . It was the second protest staged this week on Rio de Janeiro 's Copacabana beach by the group Rio de Paz . On Tuesday , the group created a mock cemetery in the sand with mannequins representing 9,000 people who Rio de Paz says have been slain and secretly buried since January 2007 . Rio de Paz President Antonio Carlos Costa said he believes that about 6,000 of the missing people were killed , many by drug traffickers fighting for territory in Rio 's slums and poor neighborhoods . Others , he said , were killed by hit squads and police acting on their own . `` In general , they are assassinated by police -- police acting outside of their regular work hours , '' Costa said Tuesday . `` They are also assassinated by narcotraffickers . The bodies are disposed of in secret cemeteries in the metropolitan Rio de Janeiro area or incinerated alive by narcotraffickers in what they call 'microwaves . ' `` To illustrate the point , demonstrators also constructed facsimiles of the `` microwaves '' that narcotics traffickers and death squads reportedly use to cremate remains of those they have abducted .
