Disrupting commerce, transit and traffic became focal points for demonstrators across the country days after the announcement that a grand jury in Ferguson, Missouri declined to indict the police officer who fatally shot 18-year-old Michael Brown.

Attorneys for Michael Brown’s family vowed Tuesday to push for federal charges against the Ferguson police officer who killed the unarmed 18-year-old, and they renewed calls for peace following a night of violent protests in which several businesses burned to the ground.
