Ending (spoilers)

For the love of God, just let it up about the poor Spanish dialogue.

ALso, I felt like it would really hurt his reputation to admit that Vanicio was the killer. After all, he just had aired a show where he said Vanicio was a great guy and was wrongly jailed. Imagine the PR hit he would take if this guy who got let out of jail because of his report would turn out to be one of the biggest serial killers of all time? it could mean the end of his career, and that was more important to him than telling the truth.
