 Unlike most towns and cities in the United States., Puerto Rico does not have local or state sheriffs, sheriff duties are instead performed by the Puerto Rico Commonwealth Marshal's Office.Many municipalities have established municipal police departments, although most law enforcement activity is carried out by the Puerto Rico Police (PPR).Puerto Rico's central government, which includes all three branches of government but excludes public corporations and municipalities, has an annual general budget that currently ranges from $8.5 billion to $9 billion in revenues and expenditures.
