What Do Private Investigators Need to Know
Private investigators deal with many different types of data on a regular basis. Crime scene investigators analyze evidence and data from a crime scene. Accident investigators analyze data about vehicles and the environment to investigate car accidents. Case after case, private eyes deal with numbers and sometimes those numbers need to be converted from one measurement system to another. Utilize the tools below to convert data from one format to another as needed.
