Over a guy in a tree stand? For crying out loud!
If you understand nothing else understand this: Prior to this incident, if you called the police about someone in your deer stand they would tell you to tell him to leave!
They would NOT respond with a SWAT team. They would not respond with the state police. They in fact, would not have responded at all except to ask if you had asked him to leave. And just asking him to leave is what set out little murderer off.
