Yes. You're talking about a specific, I'm talking about a general case. We know that this wasn't the case here because the story didn't end with "I was carted away to prison." My comment was in reference to the general case of US jurisprudence the OP discusses when she says "not only is justice blindfolded, but is blind." In the GENERAL case, you can still be convicted even if exculpatory evidence exists. And this is the point I should have emphasized: Do not assume that the mere existence of exculpatory evidence will allow you to evade successful prosecution. (But thankfully, it worked fine in this case and works in many other cases.)
