The Rev. Jesse Jackson led hundreds of protesters Friday to the Flint water treatment plant, which the civil rights leader referred to as a "crime scene."

The mile-long march began at Metropolitan Baptist Tabernacle, where Jackson, television Judge Greg Mathis, and others spoke to a packed sanctuary before heading out into the street.

Their route took them past the site of a once-mighty General Motors plant that now sits empty. Chants included, "No pipes, no peace," and "What do we want? Free water. When do we want it? Now."

For 18 months, Flint used the Flint River for drinking water. A lack of corrosion control caused lead to leach from old plumbing.

Jackson accused government officials of covering up the distribution of "dirty and poisoned water."
