get away with, to
To escape the usual penalty. This Americanism originated in the second half of the nineteenth century and at one point also meant to get the better of someone. It was still considered slangy when it appeared in the Congressional Record in 1892: “[They] will have to be content with the pitiful $240,000 that they have already ‘got away with.’”
