Can someone not please stop him.
Can someone please not stop him?
He will not be stopped.
I think it's abiguous. I know it could also parse down to "Can not someone please stop him?" but it's also logical to read it the other way, thus half of the viable interpretations of the sentence are that it's a double negative.
Can I get a strunk and white ruling please? Anny? CAN SOMEONE NOT GIVE ME A WHUT-WHUT?
