Yes, I would like to know as well. I know you are the mother of your child, and you are fully in your rights to give whatever punishment you find neccessary, but laser removal sounds extremely harsh. Not only will it put a hole in your pocket, but scar tissue (and pain) is not fun stuff. I'm sure that he's already upset that his tattoo has caused all this commotion (or at least hopefully). Besides, leaving the tattoo could also be a good punishment. Sure he wants it right now, but if it is big as you say, he'll most likely hate it as he gets older, and if it's something as lame as stars, something (as far as what I can tell from your posts) that holds no significant value our feeling to him, he will eventually hate it and think of how dumb a move he made back when he was that age.
Also, I don't mean to troll or anything, but I think raptorrex brought up a valid point. I think getting a tattoo without consent by you would be equally as bad as making him get laser removal without his consent. I've never had a tattoo (as of yet) nor have I had to get any laser removal, but I have pleanty of scar tissue, and I hate it. I don't like the thought of anyone else having to have it.
