If a forensic scientist looks at a piece of evidence with the wrong theory they might try to prove their theory by trying to get proof out of it which can cuse a domino effect to where the wrong person can be accused of the wrong thing.
- false evidence
The evidence may be planted and the forensic science can look at it the wrong way similar to misinterpreted evidence. usually forensic scientist can see that it has been planted but when they figure that it has then its even harder to look for the real evidence. and it would take a longer process.
