Crime and criminality have been a critical and major discourse in Nigeria socio-political and economy life since independence and particularly after the civil war. It seems none of the successive governments has been able to checkmate the menace to an appreciable degree [Third United Nations Crime Survey, 1993]. The failure of the state and state actors in crime control has led groups and individuals to take laws into their own hands; this assertion is corroborated by Roberts and Oladeji , who observed that the perceived failure of the State in the area of public security as reflected in non-performance of the police led to the participation of the community in security management in Lagos and other parts of the south west. The most viable manifestation of this response in south west according to them is that of the Oodua people’s Congress [OPC].
In mushin for examples The level of crime was very high before OPC involvement in crime prevention in this community. Armed robbers were too many. Even there was a time that when these armed robbers came around and their victim does not have a colour television they can steal, they subject the person to vicious beating until one becomes breathless. I want to say the level of crime was high, the armed robbers often come in group of ten or twenty to attack their victims, life was not safe until the emergence of OPC.
Thus, from the data generated, crime level was high before OPC emergence in crime control. This upward trend in crime was attested by Alemike and Chukwuma  observation, that Nigeria has witnessed an upsurge in crime during the past two decades most especially Lagos the major hob of the nation’s economic and commercial activities even the most densely populated city. The increased level of crime might also be as a result of the pervasive and persistent increase level of deterioration in socio-economic conditions of the citizens, this condition gives room to poverty, inequity, disenchantment, frustration and hopelessness that on the long run find expression in criminality.
Having known the position of crime in The South West before OPC intervention, it is pertinent to look at the position after the intervention of OPC and its crime prevention related activities. This in other words, will give a clearer view of the impact of OPC in crime prevention. Respondents were asked to state in clear terms whether crime has reduced or it has been on the increase with OPC presence. In response to this, 99.0% affirmed that crime has drastically reduced, while 1.0% was negative. Majority distinctly supported the view that OPC has helped immensely to put crime in check.
An Opinion leader provided insight into OPC impact on crime rate in Ado-Ekiti thus:
The level of crime since OPC impact on crime prevention reduced. Actually we faced some problem with the government and the people when we employed the service of OPC men but we thank God that the people later embrace OPC, because the police were unable to help the people.
