Saying because he used a forearm it wouldn't leave marks vs using your hands and that's why he got off. If they were in a drunken knock down drag out, there would be plenty of physical evidence, I believe. But that's my opinion too. Personally, from the comments I've seen I think she was at least partially responsible for the altercation and as I said, if this is the only episode and you investigate it and are satisfied with what you hear from him, I see no problem with hiring him. As I've also said, if he's an alcoholic, has a violent temper and history of domestic abuse, there will be a lot of evidence to that and then I think he shouldn't be considered.
