What must be present to prove general domestic violence.
3rd Party Impartial Witness
Without such a witness the court lacks sufficient evidence to convict, or even proceed.
I recommend, that if a person is subject to domestic violence, to install a miniature camera that is undetectable and activate it anytime they believe such violence may commence.
The reason I post this is because thousands of men are being financially, and socially destroyed weekly in our country simply because women know that all they need to do is rub there arm on a carpet and call the police and claim domestic violence, the man is off to jail for no less than six months as they wait for trial.
