(KMOV.com) -- The head of the Missouri Highway Patrol says his officers are preparing for the worst if protesters react violently to the results of the grand jury investigation of Ferguson Police Officer Darren Wilson.
Colonel Ron Replogle told reporters in Columbia that officers are taking special training to prepare for possible unrest.
The state has also ordered more riot shields and is limiting vacation time for officers.
Ferguson Police Chief Jackson told News 4 that agencies with the Unified Command Force are planning together.
Chief Jackson had planned to visit various sites in Ferguson today, including the Canfield Apartments where Michael Brown was shot and killed on August 9, to personally extend his apologies for the incident.
However, those visits have been cancelled following Thursday night's unrest in Ferguson.
