You would want to cut the ground wire. This will disable the led, and make it impossible to get "zapped" or cause a short. the only way you could cause a short in this scenario, would be to apply power to the cut ground connection. This would be called a short to ground. Most switches dealing with dc current, are switched on the ground side. This limits sparks/arcing when the switch is switched on and off.
