During the Carnival in São Paulo, undercover officers from the Civil Police employ a variety of costumes as part of a strategy developed by the Homicide and Person Protection Department (DHPP) to combat ongoing issues with cell phone theft and robbery, particularly in crowded street festival settings. The officers volunteer for this role and come from different divisions within the unit, emphasizing their commitment to maintaining safety during the festivities.

These undercover agents are tasked with identifying and apprehending known targets while also proactively deterring opportunistic thefts that often occur in the busyness of the Carnival. The DHPP explained that the officers do not remain stationary; instead, they mingle with the crowds, moving among the various blocks to blend in effectively. The need for mobility and comfort dictates their choice of attire, enabling them to navigate the festivities seamlessly.

This level of preparation highlights the serious approach taken by law enforcement to protect Carnival-goers, indicating a recognition of the real threats posed by thieves during such large gatherings. By using undercover tactics, authorities aim to create a safer environment for people celebrating the Carnival, while underscoring the ongoing challenges faced by police in urban settings during peak social events.
