taser malfunctioned, probes didn't deploy
The taser wasn't malfunctioning, that 2nd officer (tard, even look at his stance, I wouldn't want him as my backup that's ffs) was using the "drive stun" function of the X26 Taser/Conducted Electrical Weapon. The sound (crackling) and visual (sparking) are used as a de-escalation technique on their own. IF the X26 model is one of the later models, this can be done with the probe cartridge(the flying darts with the wires attached) still attached to the Taser, allowing the user to engage the "snap crackle and pop" feature while still retaining the ability to dart someone at a distance. Drive Stun is a close contact technique that requires the user to push the muzzle of the weapon into the target while it's in snap/crackle/pop mode.
