Kansas City police officials have approved policies governing officers' response to public demonstrations and the use of body cameras.

The city's Board of Police Commissioners on Tuesday approved a policy that limits the use of less-lethal munitions such as tear gas and other tactics to break up unruly protests.

Officers are required to focus on people breaking the law and allow others to exercise their free speech rights. The policy came after police were criticized for their handling of social justice demonstrations in Kansas City last year.

A second policy requires police to activate body-worn cameras in every interaction with the public.
