@hawkeye10,
Well dear Hawkeye if I found an unkown man pinning my wife down in my home and he does not stop at once when order I am going to do whatever is needed to stop the rape.
As far as it might not be what it seems that come under assuming the risk of having sex in another man home with another man wife as you do not need to be right you just need to have reasonable believes that you wife is being raped,
In Texas there was an interesting case of a man finding his wife under a gentleman in the gentleman pickup truck parked in the driveway of the husband home.
The wife yelled to her husband that she was being rape and the husband ended up killing the man.
Turn out the woman were yelling rape to cover up her fooling around and the husband was not charge with any crime the wife however ended up getting a murder conviction.
