No. I think that sometimes there's a noise made. I'm not certified in the use of a taser, so perhaps others may help you. My understanding is that when there is not a good connection.... Basically, when you fire a taser, two probes are shot from the weapon. They are attached to wires, and the impact of the device is really the transfer of electricity between those two points. If there is not good contact as a result of the clothing that a person is wearing, for example, there won't be a good connection, and electricity will not flow through the body, as the device was designed. It will be otherwise discharged, which makes this noise that you are referring to.
So if I've been tasered--by the way, since my last appearance before the committee I have been tasered--and one of the probes lodges in my chest and the other is attached to my shirt, depending on how I move, that probe will come in contact with my body or not. In fact, it might be quite appropriate for the officer to recycle the device, because it might not impact me if I'm leaning forward, but it may impact me if I'm leaning backward.
But certainly after a device is used in an incident and an incident is resolved, if there were issues around the malfunctioning or functioning of the taser, there should be testing. In fact, our policy requires that.
