Answer: both city and county governments
Step-by-step explanation:
Policing in the United States is very decentralized such that local governments have their own police services. This includes municipal (city) and county governments. This ensures that the police are more in touch with the needs of the community seeing as they are from the community.
State governments offer policing as well and the Federal government offers some sort of policing in terms of the national law enforcement agencies such as the Federal Bureau of Investigation (FBI) and the Drug Enforcement Administration (DEA).
