Wouldn’t have to be visible. The preserve was deliberately targeted. The guide (and shooter) intentionally lured the animal off the preserve to kill it. When they removed the animal’s head — they attempted to destroy the collar.
That’s like coaxing somebody’s dog off their lot in order to kill it — and then trying to destroy the dog collar.
That may be true. We do not know.
Baiting lions is legal, and a fair number of lions leave reserves and are legally killed in Zimbabwe.
What appears to be illegal in this case, is that there was no quota for a lion on that particular hunting area. The dentist may or may not have known about that.
As for the collar, not all lions on the reserve are collared. If the hunter could not see the collar, what difference does that make?
next argument?
