A fifteen-year old gang member shoots and kills a fourteen-month old baby in a "drive-by" shooting in which the defendant was riding a bike.
The baby is dead. The fifteen year old is essentially sentenced to spend the rest of his life in prison, albeit with a (slim) possibility of parole.
There's not even massive evidence that the fifteen-year old did it. He probably did. But in a perfect world, you'd want a lot more than the (notoriously unreliable) eyewitness evidence that was the basic reason for defendant's conviction.
No winners here. None.
