Like I said most people find tasing young children distasteful. It’s just not a good thing. It’s improper behavior. It goes against the fabric of our culture. It’s also unnecessary. Discharging 1200 volts of electricity into a 90 pound kid is a really poor idea.
Kids are a pain in the azz. That doesn’t mean they should be treated violently for a non violent crime. How did we ever manage to deal with kids shoplifting before tasers were invented? Are you starting to get the picture yet?
Well, the traditional method of dealing with a kid committing something which got the police involved, would have involved a thorough application of a leather belt across the butt. But I'm guessing you would not approve of that either.
For the case where mommy dearest is approving of, and instigating, the shoplifting, then I would be OK with Mommy getting the leather belt treatment instead, and then her dealing with the kid however she wanted, to avoid repeats.
