This incident has raised concerns about the police's methods in handling public gatherings, particularly in festive environments where the intent was to celebrate together.

The incident in Butantã underscores the complex relationship between local authorities and public celebrations in Brazil. As more people engage in street festivities, incidents like this raise questions about the balance between public safety and the right to celebrate culture freely.
