But, escalation is met with escalation. Even the police can increase response on increased action.
That works two ways.
All peaceful last night until the police and military showed up. They were determined to enforce the curfew, no matter what. That didn't work out well.
Like Chile when I was there last year. Peaceful protests, then the police showed up, killed and injured people with rubber bullets. One person was killed when the rubber bullet entered through their eye socket, or so it was reported (autopsy) in the press.
After that buildings burned. The police became the enemy - of 90% of all Chileans. The police finally disappeared from the protests.
The burning stopped (except for 55 gallon drums, and trash in the middle of the streets, and small bonfires where no damage would result), and the protests continued, with amazing bands, music, speeches. Businesses opened up.
On my way back, middle of December last year, 10-midnight, you could walk downtown Santiago, hear the protests, watch them march, hear the music, all while sitting outside at a swank cafe enjoying a snack, or ice cream.
My heart is still with the people of Chile.
