Just as an observation, the "circuit" made that the electricity in a Tomas Alva Swift Electric Rifle, as implemente dtoday, uses two wires between the rifle and the subject to provide a complete circuit. It does not use a link to the ground, or I assure you very few police officers would ever fire one a second time.
Additionally the "charge" is a high voltage, high frequency signal that is intended to cause the human nervous system to become less effective at the area applied. The problem with this, in the situation of a carbon fiber lined piece of clothing is that the carbon fiber provides a 'skin effect' conductor for the signal, which it will follow in preference to the effect that the barbs in the skin will provide.
That said, the two remaining problems are that you've got two metal barbs stuck into your skin with wires dangling off of them running back to the police officer, who's likely to be somewhat distressed that you are not being affected by the high voltage, high frequency (low current) signal being sent down the wires, and is likely to switch to something less likely to be 'less than lethal' in attempting to arrest you.
Hopefully your acting skills are up to the task of leaving the officer with the impression that his or her Tomas Alva Swift Electric Rifle, is being effective on you.
