and that beast took it like a champ.
Electricity goes the path of least resistance to close the circuit. As long as both prongs are in the flesh of the suspect, then it will arc entirely between those two prongs. You would only get electrocuted if you were a ground in that situation.
They might be grounded somehow.
If the cops were grounded, then they would get zapped. The cops were probably insulated and not completing a grounded circuit that was of less resistance than the taser device.
