The Most Difficult of Cases
Many are familiar with the quotation "Better that ten guilty persons escape than that one innocent suffer." Those words were written by English jurist William Blackstone in the late 18th century and are inarguably a founding principle of the American system of justice. However, as with all principles, there are always situations in which they are tested, and if it is a true principle, it is upheld and endures. Perhaps most indicative of the importance of a principle is whether it is fundamental enough to survive even the most extreme cases when it feels difficult, even abhorrent, to apply.
Thus, cases involving children as victims, the most sympathetic victims possible, are a true test of this principle. One such case was the Casey Anthony trial in Florida. The prosecution had a theory that Casey was the murderer, maybe even a theory that was more-likely-than-not to have occurred, yet everyone who was watching closely knew that if we started from the presumption of innocence, and we reviewed every piece of evidence assuming that Casey was not guilty, then there was no way for the prosecution to eliminate all reasonable doubt of Casey's guilt. No matter how much her attitude and behavior made us wish they could.
Another genre of cases that test our system's Blackstonian principle at its extremes are those involving the post-partum psychosis defense. It is likely that this defense will be used in an upcoming case in Orange County, the one involving the Sonia Hermosillo, who is alleged to have intentionally dropped her seven-month-old son off the 4th floor of a hospital parking garage.
Part of the reason why cases such as this are a test to our system and its foundation upon the presumption of innocence is because of the inflammatory nature of the details of the allegations. Everyone who hears the allegations naturally feels anger toward a mother who is even capable of doing this to her child. And it is hard to conceive of more ammunition for the prosecution in a trial situation, as they can talk about the innocence of the child, who probably asked the question, "why is mommy letting me fall?" right before his death. Or turn to the blow-by-blow actions of the defendant, as she unbuckles the baby from the car seat, holds him by his arms, and walks briskly to the far wall of the parking garage, hoists his 20 lb body on top of the concrete, then, feeling the anger well up inside her, violently pushes her son over the side.
When a prosecutor can be cinematic about the depravity of the defendant's crimes, it sears an image into the minds of the jurors, who listen to the rest of the trial, but not without that image in their heads. Then they retire to impartially deliberate, but not without that image in their heads. Are they able to overcome that image, and reach the truth of what happened by weighing the evidence impartially?
If they are not, then our system has failed. Because no matter how depraved the actions of a defendant might seem, a larger truth may always be at play. For example, with mental health defenses such as the postpartum psychosis defense, the truth is that mental health problems are real, scientifically provable, and actually alter the reality of those suffering from them to the point they might unknowingly commit horrible acts.
When facing a mental health defense, prosecutors inevitably list all the tasks surrounding the incident that the defendant performed correctly as evidence that they "knew what they were doing." This case is no exception, as in a statement to the press, the Deputy District Attorney handling the case pointed out that Hermosillo validated her parking ticket before leaving the parking garage that day as evidence that "she did know what she was doing."
But whether a defendant was capable of performing the surrounding tasks is not the issue in such cases. What matters legally is whether she knew right from wrong at the time, which has nothing to do with whether she could think rationally about such minutiae like parking tickets. Clinical Psychiatrist Rita Suri was quoted in a recent L.A. Times article explaining that while 80% of new mothers experience postpartum depression in some form, 1 in 1,000 will experience it in a severe form, wherein they lose touch with reality and can have psychotic hallucinations, often religious ones. It is therefore very possible that a mother suffering from such severe psychosis could believe she is doing the "right" thing in killing her child, and simultaneously remain able to take care of her parking fees afterwards.
Whether a mother who actually suffered from such psychosis is then convicted in court of murdering her child is a daunting test for whether our justice system will actually allow an innocent person to go free despite the most inflammatory of circumstances.
