This wasn't Vass's mistake at the lab, it was JA's mistake in asking him about the wrong can yesterday. It was JA's mistake, not Vass's. It doesn't color his work at all because it has nothing to do with his work. He did not misidentify this can when he went to process it. That is not the mistake at all. The chain of custody is intact. The only mistake was JA's in asking him to say that can was the right one. That has nothing to do with chain of custody or Vass's work. This is not a mistake to get upset over. JA has had a sterling reputation in his career and in the past three years. At least he admitted to his mistake. Baez has made millions of mistakes and never admitted or apologized for ONE of them. I trust Ashton anyday over Baez. If Baez harps on this, it's only going to make things worse for Casey.
