Some of the problems with "sting" operations by small departments, as reported by the chiefs, are lack of funding and manpower as well as the likelihood that offenders will recognize the officers involved in the "sting" operation. The most effective way to overcome these problems is for a number of departments to sponsor a joint "sting" operation. Departments can share costs and provide personnel unfamiliar to offenders in the jurisdiction where the "sting" is conducted. Usually, the chances of a successful "sting" increase with an increase in the number of departments involved. A South Carolina "sting" in December 1986 is an example of a successful multiagency operation. The U.S. Marshals Service sent invitations bearing a fictitious company letterhead to alleged offenders' last known address, informing them they would receive up to $5,000 in gifts if they came to the company's office. As an added incentive, each recipient would be transported via limousine to the office. Each limousine was driven by a U.S. Marshal. Fifty-nine persons were arrested.
