Get away with murder

Get away with murder is an English idiom, used to describe escaping the consequences of an action. While literally it refers to someone committing a murder and not being punished, it can be used figuratively of someone who is seen not to suffer the consequences of their actions: "I hate to see a mother who lets her children get away with murder".^[1][2][3][4]

It's unknown where and when the idiom originated from exactly, but is theorized to be from the United Kingdom sometime between 1200 and 1500.^[5]
