Final answer:
Vincent was exonerated from the crime at Gattaca due to unreliable eyewitness testimonies, no fingerprint evidence, and none of the stolen goods found with him, highlighting flaws in the criminal justice system.
Step-by-step explanation:
Vincent was cleared of the crime committed at Gattaca primarily due to a lack of conclusive evidence linking him to the crime. Factors that contributed to his exoneration included contradictions in eyewitness testimonies, the absence of his fingerprints at the crime scene, and the fact that stolen goods were not found in his possession. These elements raised serious doubts about Vincent's guilt, illustrating the inadequacies of the criminal justice system at the time, especially in cases involving immigrants and radicals.
