Forensic firearm examination is when experts look at guns and bullets that have been involved in a crime, to try and figure out what happened.
When someone is shot with a gun, the bullet that comes out can have unique marks on it. These marks can help experts figure out which gun the bullet came from. Experts can also look at the edges of a bullet hole to figure out how close the bullet was to the person who was shot.
When experts look at guns, they can compare marks on the bullets that were fired from the gun with marks on bullets that were found at a crime scene. This can help them figure out if the gun was used in the crime.
Another thing experts can do is look at the gun itself to see if it was tampered with or altered in any way. They can also test fire the gun to get bullet samples that they can compare with bullets found at the crime scene.
Overall, forensic firearm examination is a really important part of solving crimes involving guns. It helps investigators figure out what happened and who was involved, and ultimately helps bring justice to those affected by the crime.
