Protesters in Ferguson, Missouri, have won a settlement requiring police to restrict their use of tear gas following the militarized response to protests over the police shooting of Michael Brown. St. Louis City and County police, as well as Missouri State Highway Patrol, all agreed to requirements, including clear warnings for tear gas use. A judge will supervise the terms for three years. Attorneys say the St. Louis area will be one of just two police jurisdictions in the country with such a policy for tear gas.
