Introduction to Forensic Ballistics
Overview of Forensic Ballistics
- The video introduces forensic ballistics, focusing on the application of knowledge, methods, and techniques to investigate phenomena related to firearms.
- It encompasses scientific and technical studies of firearms, ammunition, projectile movement, effects, and direction.
- The aim is to gather evidence that aids in establishing criminal acts through detailed analysis of injuries or deaths caused by projectiles.
Phases of Forensic Ballistics
Internal Ballistics
- Internal ballistics examines all phenomena occurring within a firearm during discharge, including structure and functioning.
- It studies projectile movement from the moment it is fired until it exits the barrel, analyzing factors like gas pressure and friction.
External Ballistics
- External ballistics focuses on the projectile's trajectory after leaving the barrel until it reaches its target.
- Factors affecting this trajectory include gravity, air resistance, wind direction and intensity, as well as obstacles encountered.
Terminal (Effects) Ballistics
- This branch investigates how projectiles behave upon impact with targets—examining deformation and energy transfer.
- Effects can include penetration power, fragmentation damage, explosive reactions upon impact or perforation through barriers.
Detailed Analysis of Forensic Techniques
Identification Techniques
Identificative Ballistics
- Involves identifying firearms based on origin (brand/model/caliber), using collected ballistic elements from crime scenes.
Comparative Ballistics
- This technique employs microscopic comparison between questioned items (e.g., casings/bullets) to determine if they were fired from the same weapon.
Reconstructive Studies
- Reconstructive ballistics integrates findings from various forensic disciplines (chemistry/forensics/criminal fieldwork).
