1. Cougar is obviously closer to the (possible) truth then those who overly-criticized him based only his written word.
2. The act that some readers believe that "Cougar" could be found guilty of is not "liable." The lawsuit would be for "slander" or "defamation" for which the accusers would seek to hold Cougar liable.
3. There is no case because Cougar has not named anyone. Where is the specific malice to any specifically identified person?
4. If you do not believe that some deer hunters, including bowhunters, do not kill deer just for the sake of killing and leave the deer where they lay or dump them in a ditch, or elsewhere, you are in denial or you haven't hunted deer very long.
5. If the unnamed parties have legally killed as many deer as was told to Cougar, and have properly checked all kills in, but they are dumping some, most, or all, what is their crime? In the state of Illinois, the crimes would most likely be held to "littering, " "illegal dumping," and "improper disposal of a dead animal."
