ST. LOUIS (AP) — Seven school districts have asked the St. Louis County prosecutor to wait until classes aren’t in session to make any announcement about whether a grand jury decided charges were warranted in the Ferguson police shooting case.

Riverview Gardens School District Superintendent Scott Spurgeon last week sent Prosecutor Bob McCulloch a letter signed by six other superintendents asking that any announcement be made after 5 p.m. or on a weekend.

The grand jury is expected to decide by mid-November whether Ferguson Officer Darren Wilson should face charges in the Aug. 9 fatal shooting of an unarmed 18-year-old, Michael Brown. Brown’s death led to weeks of sometimes violent protests in and around Ferguson.

The letter suggests that any protests after the announcement could make it hard for students to get home.
