What is the basis of any defined actions (event segments) that the crime scene analyst identifies?

Each event comprises of “event segments”, which are the micro-components of the event. Event segments details the specific events that occurred at specific moments in time, more like a snapshot. The presence of physical evidence and a range of interconnections between the items of evidence will speak to the existence of any given event segment. Event segments are always distinct by specific data. The more event segments the analyst is able to outline, the more precisely he can describe the true nature of the event.

try something like republic or democracy joined or something because its talking about a election party.
