I guess it depends on perspective, and how the net is measured. If net positive _revenue_, and your perspective is stage budget (or you benefit from state funding) its a win. If the net is a calculation of revenue, public safety, and overall community, maybe not. Troopers are generally traffic and criminal law enforcement agents - public safety. Tax law enforcement may be the jurisdiction of state police in that region, but its rare to use patrol to enforce those laws. There is typically a division specific to revenue. Taking focus from patrol away from the enforcement of criminal and traffic laws and pivoting that to securing the state budget would be considered by many to be a misuse. If troopers are looking for unpaid taxes, who is looking for reckless or drunk drivers? Who is conducting area patrols where visibility is a much a crime deterrent as actual arrests? What probable cause is used to stop any car at the state border and look at receipts? Traffic violations do not provide for vehicle searches, and IIRC there are no dogs that sniff out undocumented expensed. Such divisions in jurisdiction are in place so that the "long arm of the law" does not get too long.
