Why do governments create parallel services, overlap responsibilities, rotate personnel, and carry out purges?
Parallel services, overlapping competencies, frequent shifts and purges help the leader prevent any group from gathering enough people, forces and information to threaten him. If the two services do a similar job and monitor each other, the leader can compare their reports and more easily detect disloyalty.
Frequent rotations break personal ties among the personnel, while purges show everyone the price of suspicion or disobedience. But what increases the security of the leader often reduces the ability of the state: institutions hide information, shift blame, duplicate work and fear initiative. That is why such an organization is not an ordinary administrative mess. It should be seen whether changes in personnel and competencies are repeatedly used to weaken the independent centers of power and personal responsibility for personal responsibility.
In the security sector of Serbia, researchers note the overlap of formal powers, unclear coordination centers, personnel changes and political ties that make external supervision difficult. Such a structure allows the top not to become completely independent and that information and tasks can be redirected to more loyal people or parallel channels. The consequence is a harder determination of who has made the decision and who is responsible when the authority is abused.
How the finding is separated in the matrix
The BCSP has documented through studies in 2020 and 2024 the political takeover of police, services and defence, weak parliamentary control and informal ties between power centers.
“Overlapping is not just an organizational disorder: it can be a way for a leader to compare information, prevent a competitive center from emerging, and retain the ability to reward or remove a shot.
Sources show political control and vague responsibility, but they do not reveal every secret order or internal purge.
Security institutions legitimately keep part of the data and periodically reorganize the work. The problem is political, not operational secrecy: when there is no independent supervision, a clear legal trace and consequences for abuse.
Purgatory can serve to prevent a riot, a showdown within the government or a real fight against corruption. The intention cannot be concluded without information about the targets and the procedure.

- Contribution to this answer
- Wintrobe shows that the leader constantly balances between rewards and fear and that he cannot fully know who is loyal to him. This creates an incentive to organize the security apparatus so as to reduce the risk of betrayal.

- Contribution to this answer
- Greitens shows how dictators build secret police and security structures against two different threats a rebellion from below and a coup from within. The organization of the apparatus of force therefore often sacrifices part of the efficiency to make it politically safer for the leader.

De Bruin, E. (2020), How to Prevent Coups d’État, Cornell University Press.
- Contribution to this answer
- De Bruin shows that creating parallel armed organizations can reduce the risk of a military coup because no force has a monopoly, but such a coup-proofing arrangement can have serious costs for coordination and military capability.

- Contribution to this answer
- Quinlivan shows classic coup-proofing techniques: parallel forces, kinship and sectarian ties, privileges and careful monitoring of the military. The goal is not only the security of the state, but also to prevent the apparatus of force from endangering the ruler.

- Contribution to this answer
- Hassan shows how authoritarian leaders use personnel and organizational interventions to keep state institutions under political control. For parallel services there is a broader framework, but it helps to see the same logic of personnel security.

- Source limitation
- The work starts from the concept of the captured state and is aimed at security and recommendations for reform, so its framework should be read together with wider and methodologically different sources.
