I had this happen to me once, A doe was hit by a truck two vehicles in front of me,,, A game warden was called, after approx. 35 minutes the game warden hadn't arrived yet, I couldn't watch the doe suffer any longer she obviously had a broken back with internal injuries, I knew she wasn't going to make it, I used my knife and ended her suffering. The Warden arrived after about 50 minutes and thanked me for ending her suffering however I don't know if all wardens would be so understanding, SO it's best to let them do their job.
Democracy is two wolves and a lamb voting on what to have for lunch.
Liberty is a well-armed lamb contesting the outcome of the vote.
