There are many investigative ideologies in the law enforcement community. Some of the investigative processes are different depending on the specificity of the community in which the law enforcement agency is responsible and accountable for. Each city has its own problems; thus they have a demand for specific responses. The agency is a representation of the leadership and community groups, including those who work in the criminal justice system. Inside of agencies, if there is no checks and balances, then injustices will occur.
