Palmer said in a statement on Tuesday that he didn't know the hunt was illegal, and would cooperate with authorities if they reached out to him. His hunting guide, Theo Bronkhorst, and the owner of the property where Cecil was first shot, Honest Trymore Ndlovu, appeared in court in Zimbabwe on Wednesday, and are both facing up to 10 years in jail or a $20,000 fine.
It's uncertain whether Palmer will face similar charges, or whether he knew the kill was illegal. The "trophy" - Cecil's head and skin - have been confiscated by Zimbabwe authorities.
But while it's understandable that people are mad at Palmer, who's a noted big-game hunter, that anger won't do much to bring Cecil back - or help protect the lions who are still alive.
