It will be interesting to see what happens in Brazil in the lead-up to the two big events the country is hosting in the next three years, the Football World Cup next year and the Rio de Janeiro Olympics in 2016. Those two are first-class show and TV events, the kind where any host nation wants to present itself to the world, and naturally they don't want the street kids and slums to take center stage. The police in Rio and Sao Paulo are famously brutal and they've been making efforts already to push back the slum dwellers or to plainly level some of the poor districts that are too close to city centres, working together with the mayorates there. I would sort of imagine they're likely to speed this up as the games approach.
And the same with transsexuals, transgenders and escorts. Brazil can be both embracing and rough when it comes to trans people and shemales, some of whom work as escorts, street hookers, models or adult movie actors. The whole adult and sex worker scene, of any kind both ordinary, trans, gay and fetish-oriented, will most likely get ready to reach out when the athletes and journalists arrive, while the authorities, FIFA, the IOC and many in the churches definitely don't want these people and their trade into the picture.
