I am starting to think that Hunter-nins are only a Hidden Mist Village thing. We haven't seen any in Konoha, plus they seem to send the ANBU out looking for people, something hunters are supposed to do.

I think that Mist Village had them, because they are more hardcore than Konoha. After all their Gennin test is/was killing people you knew your whole life. Until Zabuza that is...... They are just a more violent village and their tactics like body destroying, etc.. wouldn't fit Konoha.

Konoha seems to take precautions, so they don't have to kill people, like the Hyugga cursed seal.
