On December 14, following the Chamber's approval of the Dosimetry Bill reducing penalties for January 8 coup convicts, thousands protested in Copacabana, Avenida Paulista, and other cities. Artists including Caetano Veloso, Gilberto Gil, and Chico Buarque performed at musical events defending democracy. São Paulo's event drew about 13,700 people, per USP estimates.
Organized by groups like Povo Sem Medo and Brasil Popular, with MST and MTST involvement, the protests used the slogan 'Congresso Inimigo do Povo' and criticized Chamber President Hugo Motta for fast-tracking the bill.
In Rio's Copacabana, the 'Ato Musical II: O Retorno' featured MPB stars. Caetano Veloso opened with 'Alegria, Alegria' and 'Gente', joined by Duda Beat, Sophie Charlotte, Tony Bellotto and Marcelo Bonfá, Fernanda Abreu, Lenine, Leila Pinheiro, Xamã, Baco Exu do Blues, Fafá de Belém, Emicida, Chico Buarque, and Paulinho da Viola. Gilberto Gil closed with 'Aquele Abraço', 'Super-Homem', 'Tempo Rei', and 'Andar com Fé', urging more public action to improve laws. Fernanda Torres emphasized defense of forests, women's rights, and democracy. Emicida called Congress a 'handbrake on dreams.' Chico Buarque performed 'Vai Passar' and chanted 'No amnesty. No dosimetria.'
São Paulo's Avenida Paulista event peaked at 13,700 participants (12,100-15,400, per USP's Monitor do Debate Político). Guilherme Boulos labeled the bill an 'embarrassed amnesty' and urged Senate action, while supporting other causes like ending the 6x1 work scale and fighting femicide. In Salvador, left-wing deputies initially shared an outdated video, later corrected.
Bill rapporteur Paulinho da Força mocked the São Paulo turnout, boasting his pro-bill videos garnered more views (e.g., 300,000).
