content: Hey Goats, need your help and advice! Best friend who has been married for over 14 years has wife who has become unstable and is hurting the kids. Hey goats... the state I live in doesn't take audio-only recordings as evidence.   My best friend has recently started having problems with his marriage. His wife has become unstable and aggressive towards his sons. They have 4 children and they are all still in elementary school, with the oldest just entering junior high. His wife is now extremely verbally abusive to the boys and sometimes hits them. The kids are heavily influenced by the wife and his fear is that she will force them to testify on her side if he goes to court for custody without concrete evidence. The wife also hints at divorce. He wants to get evidence for child custody before the divorce actually occurs.  (He has an iphone and is trying to find a way to secretly record the abuse as final and permanent evidence in the upcoming trial. But he needs a secret way to do it with the screen off or black screen at least). Do any of you goats have ideas?
