I haven't followed this case closely because we do not have cable television either. However, it sounds to me as though the prosecution failed to present a strong enough case, and the jury did what it was legally bound to do by admitting that and declining to convict. It's a shame, then, that the prosecution didn't take the time to build their case before they filed charges. There is no statute of limitation on murder, so they had all the time in the world to make sure it was a rock solid case before they proceeded. There's no excuse for letting the media attention and emotion of the situation rush a case to court. This is what happens when you do. Do I know for sure that that's what happened here? No, of course I don't. But clearly for whatever reason the charges were filed before enough evidence was there to prove them, and that was a mistake. You hear people yowling and carrying on all the time about why someone isn't being arrested and prosecuted, when "everybody knows they did it." Well, this is why. What "everybody knows" ---or thinks they know---and what can be proven are two entirely different things, and it is certainly the prosecutor's job to know that.
If there was in fact a juror who stated that she "didn't like to judge people," then the prosecution dropped the ball there too. There is no limit to how many people you can toss off a jury for cause, and an unwillingness to "judge someone" is a big bright glaring cause.
FWIW, I would love to have seen that woman go down for whatever her role was in the loss of this beautiful, innocent child. I wish the prosecution had waited until they knew and could prove exactly what that role was.
