When my sister was 16 she lied and said that our father was sexually and physically abusive towards her. Yes he was physically abusive to the point she thought he was going to kill her. She is 21 now and is starting to tell the truth and regrets her lying on her father. She wants to tell the police and court system so our father can get the rest of his kids back but our father told her not to because she could go to jail but she doesn't care because she understands that her lie cost him everything... What should she do
