In the US we have a barely known practice of jury nullification. The jury believes the facts, but does not believe it was a crime. Thus they acquit the defendant, to nullify the law.
I did this on a jury a few years ago. We believed that the guy "pushed" the girl. But we thought that she was probably screaming in his face, so he moved her away from himself. This might have met the definition of domestic abuse, but we disagreed that it was a crime.
FYI, they were both idiots and kinda deserved each other.
