There's been a few articles over the years about some of the problems with forensic techniques. New article here about an issue with using patterns on jeans for forensic analysis https://arstechnica.com/science/2020/02 ... -evidence/

This means the technique of matching up jeans is likely to be pretty hit and miss—not catching actual similarities a lot of the time and possibly throwing up a high rate of false alarms. And that’s under controlled experimental conditions using high-quality images and jeans laid out nice and flat, not grainy security footage showing jeans being worn. On the other hand, different features like damage, branding, and size could corroborate an analysis to improve the evidence one way or another.
