In the wake of the killing of a protester on Saturday, Aug. 29, Portland Mayor Ted Wheeler has asked for ideas and help to quell the violence around the protests that have gone on in Portland for months — placing the city under a national spotlight and making it a magnet for extremists.

Mary McCord has some ideas. She's the former federal prosecutor who sued to stop the violence in Charlottesville, Virginia, after violence at the now-infamous white supremacist "Unite the Right" protest of 2017.
