I provided the law in California under which Peterson was tried. I provided the law under which the jury came back with their verdict.
The law is simple.
Murder is the unlawful killing of a human being, or a fetus, with malice aforethought.
Please observe that the law does not read: Murder is the unlawful killing of a human being, or an unborn human being , with malice aforethought.
The fetus is a distinctly separate entity subject to the laws of your state based on the links you provided.
I have asked repeatedly for you to show any other California laws that would apply that bolster your argument and you have failed miserably to do so.
Until you can provide superceding legislation that bolsters your case, i would say that your insistence that the state of California granted personhood to the unborn Peterson fetus has been shown to be false.
