How do forensic scientists identify a bullet used in a crime?

Forensic scientists in the USA use ballistics to identify bullets. They examine the unique marks left on a bullet from the gun's barrel, a process known as "rifling." By comparing these marks with those in a database and using tools like spectroscopy and microscopes, they can match the bullet to a specific gun. This crucial evidence helps solve crimes and bring perpetrators to justice.

In conclusion, forensic scientists employ advanced techniques such as rifling analysis and spectroscopy to identify bullets, contributing to the investigation and prosecution of criminal cases.
