To summarize: yesterday Electoral Superior Tribunal's president judicially ordered the police to not interfere/stop public transport vehicles during election day. But Federal Highway Police did the exact opposite in a systematic way specially today. They stopped at least 580 buses transporting people to voting locations, but also many other private vehicles. People who use public transports are generally from lower socioeconomic status who vote for Lula. This was mainly reported in Brazil's northeast region, where Lula has greatest support, but also happened in other regions.
