Spank him!
lol. Sally Lieber would frown on that, I'm sure.
You do raise a good point as this whole spanking thing unfurls here in California as well.
What about Special Education or Challenged children or teens or folks that may only respond to some physical stimulus when they are acting up.. tho rare perhaps it might be used, tyypically they may also be handled thru medications I guess, in some cases anyway.
Parents, teachers and caregivers in some situations may need to apply for waivers, or Get Out of Jail stampbook at $500 a pop or something. I'm sure the legislators will figure out something. They always do.
