What photographic evidence is essential in the case of an explosion?

When examining an explosion, photographic evidence is crucial for establishing the specifics of the incident. In particular, photos of the device label provide clear identification of the explosive material or device that caused the explosion. This information can be critical for forensic analysis and for understanding the nature of the explosion, including the type of device used and its potential origin.

Photos of the device label help investigators link the explosion to certain manufacturers, models, or types of explosives, which can lead to a deeper understanding of how the explosion occurred and whether it was accidental or intentional. This evidence can also be foundational in court proceedings when establishing the facts of the case.

While documenting the presence of gas lines, names of witnesses, and the extent of damage are important in an overall investigation, they do not specifically pinpoint the operational details of the explosive device itself like the photos of the device label do.
