Protesters across the country are planning demonstrations even before they know whether a grand jury has indicted a white police officer who killed a black 18-year-old in Ferguson, Missouri.

Activists are scheduling marches and rallies from Los Angeles to New York to coincide with the announcement of the grand jury's decision expected to be announced Monday evening. The panel was considering whether Officer Darren Wilson should be charged in the shooting death of Michael Brown.

The racially charged case has inflamed tensions and reignited debates over police-community relations in many cities.

Clergy are planning to hold a gathering at a church in Denver, where a jury found deputies used excessive force in the death of a homeless street preacher.

In Cleveland, at least a dozen protesters held signs and chanted about recent police shootings there.
