On May 21st, an event was scheduled where protesters would call for the decriminalisation of marijuana.
Protesters turned to social media, blogging the crackdown and the violent response from the police. Outraged, the following week, on May 28th, citizens from many groups beyond cannabis supporters joined together to organize a new, broader march for freedom of expression.
Drawing inspiration from the #spanishrevolution, more than 5,000 protesters gathered for the #MarchadaLiberdade - the March for Freedom - shouting "Spain is here!"
[Translation: Social media has changed the world. The TIME HAS COME FOR BRAZIL! 18/June will be the #MARCHAdaLIBERDADE!]
[Translation: Right of expression, the right to come and go, the right to live. I SAID TO LIVE, AND NOT SURVIVE!]
[Translation: We are all elderly, indigenous people, transvestites. We are all from the Northeast, Bolivians, Brazilians.]
[Translation: Why is this #marchadaliberdade so prolific? Why do they not just protest strongly against the numerous taxes.]
[Translation: First they ignore you. Then they laugh at you. Once you attack. And then you win.]
The Stream spoke with Felipe Altenfelder, who is helping to plan the protests, about what to expect this Saturday.
