Okay kiddo, have you ever seen a puzzle? Every piece of the puzzle is different and unique, right? Similarly, every bullet and gun is also different and has its own unique shape and markings.
Now, when a crime is committed with a gun, the police officers need to find out which gun was used. This is where the Association of Firearm and Tool Mark Examiners come into play. They are a group of experts who study guns and bullets to solve crimes.
They look at the bullet and the gun used in a crime and compare the markings on the bullet to the markings on the gun. If the markings on the bullet match the markings on the gun, then they can say for sure that the gun was used in the crime.
This process can help catch criminals and keep people safe. The Association of Firearm and Tool Mark Examiners are like detectives who study guns and bullets, just like how you solve a puzzle by finding matching pieces.
