The city of Key West is the only municipality with it's own police force. The Key West Police Department enforces state law, and city ordinances within the confines of the southernmost city. We are lucky here in Monroe County because the incidence of violent crime is low, and crime overall in the county is not a major problem. A large number of the crimes which do occur here are tourist related, however. Unfortunately, any major tourist destination also attracts people who prey on tourists.
Most tourist related crime is easily preventable.
If you are staying in a hotel or motel, lock your doors even when you are in the room. It tempting to leave the balcony doors open at night to enjoy the tropical breeze, but doing so is an invitation to burglars. Lock your valuables in the hotel safe when you leave the building. If you go out at night, stay in lighted, populated areas. Although we have very few areas which are considered to be dangerous after dark, it is best to take these precautions just in case.
