[1/2] Security forces operate as supporters of Brazil's former President Jair Bolsonaro demonstrate against President Luiz Inacio Lula da Silva, outside Brazil’s National Congress in Brasilia, Brazil, January 8, 2023. The battalion of troops assigned to guard the presidential palace did not respond either until rioters had entered and trashed the palace, according to a Reuters witness. Four on-duty staffers from the National Security Adviser's office (GSI) were quickly overwhelmed inside the presidential palace and their office ransacked. Presidential Chief of Staff Rui Costa said the government now faces the challenge of undertaking a "decontamination" of the security forces and holding those responsible accountable. "This excessive participation of the military and military police in politics is progressively leading to ideological contamination of the forces," Costa said.
