When forensics or forensic sciences are mentioned‚ most individuals think about the crime that forensics entails. The gore‚ the blood splatter analyses‚ bullet projections‚ DNA analyses‚ death investigations‚ semen stains‚ bite marks‚ and rape kits to name a few things that involve forensic investigations‚ but those things are just a small part of a much larger picture. Forensics is extremely broad. Forensics is the application of the scientific method and biology‚ chemistry‚ computer science‚ and
