Innocent in the eyes of the law, meaning what? No prior convictions? Not convicted of the crime for which the police officer is looking for the perpetrator? Of course they're not; they haven't even been arrested yet. And once they're dead, nobody's going to bother to prosecute and convict them.
For example, we recently had an armed robbery outside a bar here. Police came looking for the perpetrator. They found a man who they suspected might be the robber. He ran from them. They chased him. He turned around with a gun in his hand. They shot and killed him.
Now: Was he innocent in the eyes of the law? He wasn't convicted of that robbery. He wasn't even arrested for it. They would have arrested him (or at least detained him), but he fled, and then turned around with a gun.
So I'm not sure that "innocent in the eyes of the law" says very much. Other than escaped prisoners, everyone the police encounter is innocent in the eyes of the law, at least on the issue for which the police are confronting them.
