I have formerly worked with victims of assault in the immediate aftermath and that child's blood spatter pattern looks authentic to me. Her left eye is bloodshot, the bleeding has stopped and the area above her top lip has been wiped, as you would if you were pinching a nose to stop the bleeding. There are smudges in the blood and it's mostly a darker shade of red (though this could be the colouring of the photo) which indicates it was starting to dry. And when, in films or for fancy dress, people put fake blood on, they put it on to mimic what blood would do, so if you've seen blood spatters in films etc then, although the effects would be ramped up for dramatic purposes, generally they are done to be as realistic as possible.
The blood pattern is not consistent with a big spontaneous nose bleed, because the child was being assaulted and presumably not standing still - comparisons with a standard nose bleed are redundant imo.
I think Jade Binch's behaviour was disgusting. Any adult assaulting a child should receive a custodial sentence, no matter how full the prisons are. I think if it were a man causing similar injuries he would be more likely to have gone to jail and I think that Jade Binch should have too.
That poor child. Jade Binch is violent and belongs in prison imo.
