In case you didn't hear, there're a series of protests occurring in Brazil right now.
People -- young people, mostly -- are angry and taking to the streets to protest against bus fare prices and huge spendings on FIFA's Confederations Cup and the World Cup.
But, really, this post is just an excuse to use that tag.

Didn't the government give up it's bus fair increase? I guess what a protest is about is always more than the specific thing that the protesters name.
