Ferguson prepares for Michael Brown shooting grand jury decision

FERGUSON, Mo. (KABC) -- The grand jury decision on the fatal shooting of Michael Brown in Ferguson, Missouri could happen at any time, and the community is bracing for potential violence after it's announced.

Michael Brown was shot in the St. Louis suburb of Ferguson on Aug. 9 after Officer Darren Wilson, who is white, ordered Brown, who was black, and a friend to stop walking in the street.

Activists want Wilson charged with murder, but the grand jury could choose manslaughter or no charges at all.

The shooting of the unarmed 18-year-old led to sometimes-violent protests.

Friday night, Brown's parents returned to St. Louis from Geneva, Switzerland where they testified about human rights before a United Nations commission.

Attorneys for Brown's parents urged demonstrators and police to avoid violence once the decision is announced on whether to indict police officer Darren Wilson.

Schools in the Ferguson area will get at least three hours' advance notice so that students can be safely transported home and campuses can be secured.

Many churches plan to open their doors, offering prayer, shelter, food and a safe sanctuary for protesters, residents, schoolchildren and others who may be affected by potential unrest.
