What is the purpose of using evidence such as the cracked screen cover of a device?

The purpose of using evidence such as the cracked screen cover of a device primarily relates to establishing the condition of the device. This condition can provide important insights into the circumstances surrounding a crime or incident. For example, the state of the screen cover might indicate whether the device was involved in a struggle, dropped, or damaged during an event of interest. It can serve as physical evidence that contributes to understanding the timeline or interactions involved in the case.

Additionally, assessing the physical state of a device can lead to other investigative avenues, such as whether the device was tampered with or how it was used prior to an incident. The cracked screen cover can therefore be part of a broader collection of forensic evidence that helps build a narrative, corroborate witness statements, or establish timelines in an investigation.
