The advent of the coronavirus pandemic marked a watershed in Nigeria's socio-economic and political milieu, as it created panic in states. Security governance is one of the ingredients of peace and stability in society, but problems sometimes emanate from law enforcement lapses. This paper examined Nigeria's security governance dilemmas during the lockdown enforcement aimed at curbing the spread of COVID-19 and highlighted the key lessons from the government's approach to security governance during the period. Data are gathered through in-depth interviews, media reports and secondary sources. The qualitative paper combined non-killing theory and social contract theory. There were looting of shops, robbery, and killing by security forces, in Lagos, Warri, Aba, Umuahia and other cities during the lockdown owing to the problem of footprint/ access. The findings revealed that, despite surveillance efforts, security governance was undermined by the activities of idle youths, non-state armed groups, and unprofessionalism of security forces. While there was a remarkable decrease in crimes compared with the pre-COVID-19 period, the lockdown did not deter troublemakers from engaging in violent acts, such as armed robbery, police violence, and kidnapping. Adequate palliatives should be provided first at high-risk areas during future lockdowns to prevent security threats.
