“Cops have no duty to protect any adult or child. “
If that’s the case, these people shouldn’t be cops. I can give a hundred examples of cops, sheriffs, deputies and peace officers protecting adults and children. If some cop can’t live up to that standard, he should’nt be a cop or sheriff.
Only a simpering cop would whimper that he has no duty to protect adults and children.
There is no legal obligation to be every single individual's personal bodyguard. If you don't think your life is worth protecting then why should government mercenaries care about it.
