...Don't shoot!

Far from the MaracanĂ£, where the opening of the 2016 Rio Summer Games took place, about 1000 protesters rallied against mega-event overspending and for better public services.

While demonstrations were mostly peaceful, the latter portion was punctuated by stun grenades and tear gas. "There were hundreds of police, there was a calvary, there were helicopters," RioOnWatch.org's Theresa Williams told us. "It was very intimidating."
