A murderer kills one person. It's clearly illegal and everyone agrees.
However, the posse is made up of several men who are taking the law in their own hands. They make people wonder who is right and thus make the authority of law weaker.
What is an explanation when someone says:
"The our crime's worse than a murderer's. His act puts him outside the law, but keeps the law intact. Ours would weaken the law."
P.s. These men are forming a posse to hang a gang that killed one of their townsmen.
