This. There's so much manipulation going on, what with the sob stories, audience being directed when to stand up and cheer, etc., even the Golden Buzzer is a bit of a manipulation. The judges should give their verdicts and opinions on the acts and that's it. Not publicly promising backstage deals and further promotion on a personal level.
The wife is the one with the red mark on her body (somewhere), not him. None of us were there, but the LAPD responded to a call, and that is the outcome with them, complete with handcuffs. If Mrs. Ketterer starts taking the blame or saying it was all a misunderstanding, then it will show she's been a battered woman and is exhibiting signs of BWS (battered woman's syndrome).
