Shortly after being re-elected in 2019, Loudoun County Board of Supervisors Chairwoman Phyllis Randall proposed transitioning policing to a new police department while the sheriff would only be responsible for court related duties as is done in Prince William County and Fairfax County. Randall said the reason she proposed this is "I just simply don’t believe that law enforcement should be political."[3] However, Sheriff Michael L. Chapman has stated that "[Loudoun Residents] are happy with the service they are getting, and it’s almost like, 'Why is there going to be a move to try and fix something that’s not broken?' it just seems to me to be a matter of just exercising power and control."[4]
In 2012, the Board of Supervisors asked for a report about a potential transition and the commission responsible strongly recommended keeping the current system citing decreased state funding due to low crime rates and the idea that a police chief would be equally political when appointed.[5]
To implement a police department a referendum is required and must be approved by voters in the county and enacted by the Virginia General Assembly.[6] [7]
In 2022, the Board of Supervisors announced that it would no longer seek the transition following an extensive report on the subject was released by the International Association of Chiefs of Police. The report recommended that the transition not go forward due to several reasons, including the cost (estimated to be between $200 and $300 million), the LCSO's very high satisfaction rates among county citizens, and the low crime rate of the county.[8]
