Because it is hunting, not slaughter.
Most hunters are not successful.
The State issues more tags to make sure they harvest the number they want.
They monitor the number harvested, when it appears they will reach the desired harvest, they stop the hunt.
There is a 24 hour lag to report, so the hunt is not precise.
But 216 is very close to the goal of 200.
Some members of the tribal council want headlines, and to "stick it to the man", so they refuse to issue the tags they are allocated to tribal members.
Here in Nevada the anti bear hunting group floods the tag lottery with people that don’t intend to hunt. Consequence is the Sate issues more tags. Which they make money on so everyone is happy - well, except those that don’t want the hunt to happen at all. The PETA types are starting to apply the same technique to deer and pronghorn hunts.
