Brazilian Protests: A "No" or a "Go"?

In an op-ed in the NYTimes, Roger Cohen writes about the similarities between the Brazilian protests and those that have taken place in other countries around the world in the past year or two:

"Small spark, large conflagration; disoriented leader, leaderless movement; vertical rigid state power, flat nimble protests; harsh authority, impish youth; force of the state, flexibility of Facebook; police crackdowns, agile regroupings; conspiracy charges, humorous ripostes."

He writes about the challenges facing protest movements which lack political leadership, but concludes with this:

"From Tunis to Istanbul, from Cairo to São Paulo, something essential has already happened. Fear has fallen. That in itself is a game-changer."
