Idaho Falls is a city of less than 60,000 residents in southeastern Idaho.  It is located along an interstate highway, which police say contributes to the prostitution problem in local hotels.  In a reverse sting occurring in 2011, the Idaho Falls Police Department arrested four men at a hotel in a web-based reverse sting.  The operation was somewhat different than a standard web-based reverse sting:  in this instance, police arrested two women who were selling sex online.  The arrested women cooperated with police to conduct the reverse sting by continuing to run their online advertisement.  Men who called their phone to arrange to buy sex were asked to meet at a hotel, where they were arrested by Idaho Falls police.
