MIAMI — The city of Miami has suspended and intends to fire its police chief, Art Acevedo. Miami's city manager Art Noriega sent Acevedo a memo Monday listing the reasons for his termination. Noriega said the police chief failed to follow department protocols, he had lost the confidence of his officers and had made improper comments that damaged community relations. Acevedo came to Miami after gaining a national profile in Texas as a police chief in Houston and Austin. At a news conference announcing his hire in April, Miami Mayor Francis Suarez called him "the best chief in America." After taking the job, Acevedo quickly made some controversial moves . He fired two high-ranking officers and demoted others. He also started getting into conflicts with members of Miami's city commission. The growing criticism of Acevedo came to a head last month when, at a morning police roll call meeting, he referred to the people running the department as " the Cuban Mafia. " Miami's city commission
