AB499 in CA could be a first step. It lets 12 yos consent to STD prevention medical care like the gardasil vaccine without parental involvement or notice.
Now this is interesting on a number of levels.
Where does a 12 year old get the money for STD prevention medical care or for that matter even a doctors visit?
Well the obvious answer is his/her adult lover is footing the bill and supplying transportation.
So legally any doctor supplying this care is required to report this abuse to the police or child welfare authorities.
So one of two things would happen in such a case; the doctor obeys the law and reports the child abuser and he goes to jail and the parents find out or the doctors do not report the abuser and the child gets the treatment and the abuse continues. For the law to make sense it would have to circumvent the requirement for doctors to report child abuse.
The other law that must be rendered mute as you alluded to is the age of consent. How law makers can conceive of changing this law simply boggles the mind. How can a child of 12 be considered to capable of informed consent to an adult sexual relationship is beyond my imagination.
