With kids involved many of the rights you normally have are removed. Police and DCS can use your silence (or a pile of dirty laundry, or you asking for a lawyer to be present, or anything they want) as a reason they need to take your child and put them in foster care, claiming that they see your actions as attempting to hide abuse or withhold access to the kid for investigation.
