When framing an argument regarding some belief, the analyst always sets a foundation, a basis for the opinion offered. This basis is generally made up of a series of premises-statements regarding the context of the scene. Framing this concept in terms of Event Analysis, each event segment is a statement about some action-an investigative conclusion. For each segment, one or more data elements are offered in support of the action-premises that support that specific investigative conclusion. The event segment (the conclusion) is derived from the data (the premises).
