LIBERTY, Mo. (AP) — Although authorities have been encouraging people to wear masks to slow the spread of the coronavirus, many police departments leave it up to officers to decide whether to cover their faces while interacting with the public.

Some cities, including Chicago, Los Angeles and New York, require police to wear masks in most situations, but law enforcement officers elsewhere are exempt from such protocols.
