1.rubber bullets are able to kill at this range (they aren't injury "free" like that)
2.the weight of the weapon would limit her maneuverability and with multiple targets all armed and skilled (assuming they have done his before - seeing how they are willing to kidnap a duke's kid)
2-5. she would have definitely lost due to adrenaline kicking in and other possible "maybe" factors
2-7. something also annoyed me - what if the enemies threw their weapons???
