Unfortuantely, children being mistreated while in the system happens every day. Maybe and this is a Huge maybe, if your child had died, you might find an attorney to take the case, but even in those circumstances, it is highly doubtful.
There was a reason your child was removed. CPS doesn't remove children because they have nothing else better to do. It is obvious there is much more to this story and we don't need to know about it. I don't know who is telling you that CPS or the police told them things about you, your child, your case. But, even if that had happened, which I serioulsy doubt, there is nothing you can do about it.
You need to work on being sure that the problems that lead to the removal of your child are corrected. CPS doesn't have the time to "stir up crap" as you put it.
