Kidero is obviously lying.
First he says he has no recollection.
Secondly he says she grabbed his nuts. Now ask any man what the natural reaction would be if his nuts are touched. Naturally you'd bend backwards, pushing your crotch in sticking your ass out with your hands, protecting like footballers during a free kick. Kidero looked very still to the moment.
Thirdly, which man reacts by slapping? I can bet you that this man has done it before so it's a matter of time before other women he has battered come out of the woodworks.
BBI will solve it :)
