Looks awful...but if you're looking for a possible why....
The pictures of the 11 year old victim covered in blood were released to the Times by the victims mother. It doesn't necessarily follow that were trial evidence. She has no black or bloodshot eye in that picture.
Binch states in interview: "The information she is stating is not true. I was convicted of assault by beating which can mean as much as a finger being put on somebody else. I haven’t beat her daughter, the information is incorrect. " So she was convicted of assault, but seemingly not the assault that caused the bloody injuries pictured. If she was convicted of assault for poking her in the chest, or pushing her, then a fine would be appropriate.
No insider knowledge of the case, but blood dripping down both arms and no swelling or visiable damage to facial features? I know noses bleed but she's obviously spread that all over herself.
Please don't think I'm suggesting that it's 'not that bad' to assault an 11 yr old. Just that conviction doesn't mean worst case scenario.
