Guerilla Instructor's Legal Fund Donation

My 25yo fiancé and her siblings have been victims of domestic violence at the hands of their retired cop father since they were children. I have so far successfully removed all of them except the youngest sister from the home. There is an open cps investigation into thier abuse of her. She is 17 and is currently in fear for her safety and is being deprived of food. As a direct result of my interference in his abuse the father has fabricated threats from me towards his life and has somehow issued me an order of protection. This strips me of my ability to legally possess firearms. He has previously threatened mine and my fiancées lives and is attempting to seize custody of our 1 year old son.
We need help with legal fees so we can beat this in court. - Guerilla Instructor
