Dozens were arrested and several were hurt, including 17 police officers as protesters clashed with police Saturday in the Loop.
"Why is it necessary to put on social media because all it has created so far is harassment to these individuals and nothing else in the community other than more distrust and more division," said Ald. Byron Sigcho-Lopez, 25th Ward.

State law does require law enforcement to release identifying information of arrestees, but Ald. Sigcho-Lopez and others say proactively posting it on social media was out of line.
"It shows even at the highest level of the police department they are implementing bad judgement," said Berto Aguayo, founder of the anit-violence group Increase the Peace.
Facing a backlash, CPD deleted all the tweets except one. The department has since said it will no longer include residential addresses of offenders in social media posts to protect their privacy.
Besides changing policy on tweets, Berto Aguayo says police must review their tactics last weekend. Aguayo, who participated in the protest, says he was peppered sprayed and hit with a baton.

"It was almost like an abusive parent showing who is boss in the house. [It was] completely horrific because it was a bunch of kids organizing their right to peacefully assemble," Aguayo said.
Moving forward, Aguayo and Ald. Sigcho- Lopez says there must be a city-wide plan to make sure police and protesters can co-exist peacefully.
