She can threaten all she wants. If there is insufficient information for them to shelter your child, or do a direct file, then there is nothing she can do. Let her threaten. They have to prove that you did something wrong, and it sounds as if you complied and showed that you did not. Sometimes the investigators are a little over the top. In any case, the standard is not simply drug use, but drug use that harms your child - either using around your child, or using in a manner that impairs your ability to care for your child. As to violent behavior, if all those people lived there, then surely someone else would have seen it. If you are still concerned, you have a right to get an attorney to represent you and to tell them to back off.
