Um.... you do know why Tazers work so well right? They would literally be unable to control muscles. And you're using one instance that was very improbable to begin with like it happens a lot.
Considering that the universe is becoming increasingly unstable and that our foes have included sentient sounds, supernatural beings and the creations of psychic crystals, I have a feeling that improbability isn't the best argument.
I'll give the point to you when an whale falls out of the sky with a bowl of petunias.
Anyways, I feel it would be useful so that it disables enemies from using the most wide spread (I mean, they gave them out prisoners) form of mind control. I say fuck people who think mind control prevention, it needs done. May I point back to the previously mention cultist mission where a good chunk of people nearly died due to someone being on an MG and getting MCed?
