Forensic science is unreliable
Forensic science has been unreliable for decades. Many methods, including hair analysis, bite marks, and even fingerprints, have been proven inaccurate or unscientific, leading to wrongful convictions. DNA is powerful but also susceptible to contamination and interpretation errors.
- 🔬 Microscopic hair analysis, once used in hundreds of cases, was found to be wrong 96% of the time, with examiners sometimes confusing human hair with dog hair.
- 🦷 Bite mark analysis has no scientific basis and skin's distortion makes it an unreliable medium for matching.
- 🩸 Bloodstain pattern analysis, based on trigonometry, failed to account for gravity and drag, leading to incorrect conclusions about events.
- 🖐️ Fingerprint analysis relies on subjective identification of 'minutiae' (ridge details), leading to errors and bias, as seen in the Brandon Mayfield case.
- 🧬 DNA analysis, while powerful, can be compromised by trace DNA transfer and contamination, as exemplified by the case of Lucas Anderson.
