Chicago police monitored black protest leaders after Ferguson

Last fall, as a grand jury investigated the shooting death of Michael Brown in Ferguson, Missouri, the Chicago Police Department began monitoring African-American groups and activists in Chicago, records obtained by the Chicago Sun-Times show.

The police tracked protesters' posts on social media and kept a log of demonstrations around Chicago, some with no connection to Ferguson.

That log included a meeting of the Rev. Jesse Jackson's Rainbow PUSH Coalition, a protest calling for raising the minimum wage and a "Fur Free" march on Michigan Avenue.
