I was wondering whether there is any English proverb, idiom or expression which can be used to describe the situation in which someone behaves in an unfair way to you, for instance by blaming or criticizing you unfairly. For example, let's say something wrong has been done by someone else which has made one of your friends so angry. He/she (your friend) comes to the company (group of people) which you are in and puts all the blame on you out of all other people who are there (at that company and at the same time,) without being sure whether you had done that. You get shocked because you know that you have been absolutely innocent and say:
- (Literal description): Didn't you find someone else to blame?! (said sarcastically in a surprised tone.)
I wonder what a native speaker would probably say here to show his/her surprise and bad feelings toward that behavior as a proverb or fixed expression or an idiom?
