We generally work closely with Law enforcement agencies and governmental agencies and do not experience any lack of cooperation due to our company reputation along these lines. This is extremely important in working on domestic violence case, and other cases of criminal intent or endangerment as the police departments and governmental agencies need probable cause to conduct an investigation therefore a lot of cases that can be brought to law enforcement and governmental agency now can be addressed based on the evidence provided to them so that as now they have probable cause on issues that licensed detectives and investigators have provided.

Police departments are generally set up to respond to crimes committed and the services of a detective agency provide investigations into complaints that can be checked out prior to the crime being committed. We also provide investigation after the crime is committed even though the police were or are still involved.
