As a police i will go for the law first. if my mother committed the crime, should be punished. since this what my mother had taught me.
but I am 100% sure, my mother will not voilate any rule in any case.
I think I would! At least I'd know she's with me and I can treat her right. Also, I'd be sure she's innocent and I'd have no problems picking her up. If it's not me, it will be someone else anyway, so just go for it.
