From looking at powerpoints, matching ballistic barcodes, and using real ballistic matching tools, I have learned that analyzing ballistics is hard. The barcodes matching was easy, but matching ballistics with real tools and real bullets was difficult.
A lot of the bullets we looked at looked similar to each other, so it was hard to differentiate between them. The grain on the bullets were similar and it was hard to match the bullets that way. The marks from the gun that were left on the bullet made each bullet unique. The striations created a unique pattern on each bullets which could be used to identify which gun they came from.
Overall, this was an interesting lab to do. It was really hard, but it was interesting to see how actual forensic technicians analyze bullets.
