The gun from the crime scene shows tool marks where the serial numbers are ground off. There are also tool marks on the bullets left behind. What information can the tool marks on the bullets and gun provide about the crime? What type of evidence does this information provide, individual or class?

Answer: Individual

Class characteristics are those features which can be common in objects constructed from the same machine. Like the shape and size. Individual characteristics are those features which can be found on the object due to it's wear and use. These can be random tool marks, like scratches, scrapes and lines.

According to the given situation, the bullet and gun are expected to have tool marks which could have produced by wear and use. Therefore, this information provide individual type of evidence.

it provides that whoever did it was pretty smart to grind the serial number off of the gun they used and the bullets that way a make couldnt be traced back individual i guess
