MILWAUKEE — Gov. Scott Walker says the Wisconsin National Guard is prepared to respond to any unrest that might occur following an announcement on whether to charge a police officer who fatally shot Dontre Hamilton in a Milwaukee park.

Walker says he fully expects any demonstrations to be peaceful — but nonetheless is prepared to call on guard members if protests get out of hand. He says the National Guard has been meeting with law enforcement in the Milwaukee area.

Hamilton was killed April 30 after a confrontation with Officer Christopher Manney at Red Arrow Park. Manney was later fired. Milwaukee County District Attorney John Chisholm is expected to make a decision soon on whether criminal charges should be filed against Manney.
