1. If you report it and you're wrong, you could ruin the guy's life. 2. If you don't report it and you're right, that poor woman is being beaten. I wish the system wasn't the way it is. The guy shouldn't be dragged through the dirt if he isn't beating his wife. My conscience would probably make me report it. Like what was said above, only report exactly what you know. Maybe mention a well-being check. I probably wouldn't report it while they're fighting. That'd only escalate things. Maybe the day after while both have had time to calm down. Just my opinion.
