"Felony murder" also applies when, for example, police responding to an alleged crime kill people while doing so. That is to say if, for example, someone is suspected of shoplifting and the cops are called, and those cops run a red light and T-bone a car, killing the occupants, the alleged shoplifter gets charged with murder for the people the police killed. Or if two people commit a robbery and the police open fire wildly, killing one of them along with several bystanders, the survivor will be charged with murder for all the deaths caused by bullets fired from guns belonging to the local police department.
