The logic to me is that parents should have the right to tattoo their children. And why not?

NC Mother in trouble for tattooing 11-year old daughter
Looks like another parent is in trouble for inking their underage child. Thirty-year old Odessa Clay of North Carolina is in trouble for tattooing a heart on her 11-year old daughter. Sporting several tattoos herself, Clay administered the tattoo in her own home. Assuming that tattooing was on par with ear-piercing for young girls, she ignored that state law that prohibits minors having tattoos.
