I read this and really don't know what to say. I just asked my 15 year old about this and it sounds like he is aware of these parties too. I would think that if you can find out who did this you could file a police report and file a complaint with the liscensing department (state) for tatoo artists. If you can find out who it was your possibilities would range from criminal charges to civil charges and suite.
Not so sure on punishment of your daughter. Sounds like she already has rebel tendancies and believes she is an adult. Maybe it is time to start treating her like an adult. Stop doing anything for her other than providing a roof over her head. She wants a car, pay for it herself, clothes, pay for it herself. You get what I mean, other than a roof and food in the fridge, provide nothing. No laundry service or chauffer service. Heck, charge her rent. If she thinks she can make adult decisions she needs to know what being an adult means. It might open her eyes. I was this awful child that did everything she wanted to. It was difficult to punish me, these are things that would have and did make a difference.
I wish you luck!
