CSI - Fingerprints
At approxamately 52 minutes into the episode they show a "10 card"(finger print card) from an prior arrest of a current suspect. the error is the top 10 fingerprints are oval, the problem is the top 10 fingerprint boxes should have rectangular fingerprints because the finger is rolled across the box when printing, making it rectangular. this is so the sides of the print can be compared.
