Its better than that. According to the law a private citizen can use deadly force to prevent their Escape.

We therefore hold that from this date forward the use of deadly force by a private person in order to prevent the escape of one who has committed a felony or has joined or assisted in the commission of a felony is justified only if the felony committed is treason, murder, voluntary manslaughter, mayhem, arson, robbery, common law rape, common law burglary, kidnapping, assault with intent to murder, rape or rob, or a felony which normally causes or threatens death or great bodily harm.[3] We also note that for the use of deadly force to be justified it remains absolutely essential, as before, that one of the enumerated felonies has been committed and that the person against whom the force is used is the one who committed it or joined or assisted in committing it. Commonwealth v. Duerr, 158 Pa. Superior Ct. 484, 45 A.2d 235 (1946). If the private citizen acts on suspicion that such a felony has been committed, he acts at his own peril. For the homicide to be justifiable, it must be established that his suspicion was correct.
So according to this if you are robbed just wait for he perp to turn around and run away........Then you yell STOP and unload a magazine in his back.............

Totally legal. What can go wrong?

And if anyone does any mayhem you can pop a cap in them too.......Gotta love it here in Pa
