Explanation:

During the 17 year reign of Siaka Stevens which was tagged 17 years of plague of locust witnessed the destruction of institutions in Sierra Leone. Judiciary was undermined and corrupted, police and military was used as instrument of cohesion, the treasury was looted through sponsoring of pet projects to political insiders. Opponents were either sanctioned or sent on exile. Siaka Stevens was authority to himself.

When Siaka Stevens handed over to Major General Joseph Momoh, who was grossly inept and lack any sense of leadership, things went from bad to worse. Basic needs like goseline were in short supplies, government could not pay salaries. Every available resources was up for looting and these went on unchecked.
