What type of data does the "Criminal History" file in NCIC hold?

The "Criminal History" file in NCIC is designed to provide comprehensive information regarding an individual’s legal encounters. This includes a complete record of criminal activities, which encompasses arrests, charges made against individuals, and any convictions that result from those charges. The ability to access such detailed historical data allows law enforcement officers and agencies to make informed decisions during investigations and enforcement actions.

The other options do not accurately reflect the breadth of data found in the "Criminal History" file. For instance, limiting the data to only convictions would overlook significant aspects such as arrests that didn’t lead to a conviction, which are crucial in forming a complete profile of an individual’s criminal actions. Civil cases and traffic violations do not fall under criminal history in the NCIC context, and focusing solely on active warrants also fails to capture the full scope of an individual’s criminal record as held in the file. Therefore, the correct understanding of the "Criminal History" file within NCIC encompasses all elements: arrests, charges, and convictions.
