As far as I know, "get away with" means not being punished for something. For example, I succeeded in getting away with fines for blowing the red light.

"Get away with something" means to manage to do something bad without being punished or criticized for it: They have repeatedly broken the law and got away with it. to do something successfully although it is not the best way of doing it: Do you think we could get away with just one coat of paint on that wall?

It means that you are not punished for doing a crime or something wrong. He could get away with murder....This is an idiom meaning :he is so cunning, that no-one would be able to catch him for murder.

It means to something not nice (like murder, theft) and escape punishment
