OpusatFR's reply on this thread is gold.
What he is trying to prevent is the stereotypical young, scared, girl who gives birth, abandons the baby to die, and later claims that it was born dead. As of now, there is no way to prosecute them, as the coroner must examine the baby within twelve hours to determine if it was born alive or not.
Due to poor drafting of this bill, what came out was that you had to report all miscarriages or face prosecution (due to the definition of "fetal death" in VA). He now sees the error of his ways and is going to draft a bill that makes sense for submission in the next session.
