What are the four different levels of proposition that evidence addresses in forensic analysis?

The four different levels of proposition that evidence addresses in forensic analysis include the Source level, Sub-source level, Activity level, and Offence level.

At the Source level, forensic evidence seeks to identify the origin, such as the person or object responsible for producing the evidence. The Sub-source level further narrows this down by examining specific aspects of that source, such as individual characteristics or details inherent to the source itself. The Activity level investigates the specific actions or events that produced the evidence, establishing the sequence of events or behavior associated with the source. Finally, the Offence level deals with the broader context of the criminal act, tying together the evidence to the alleged crime.

This framework is essential for forensic analysts as it helps in systematically organizing and understanding the evidence and its implications effectively. Each level builds upon the previous one to create a complete narrative of the incident being investigated.
