You know that is so true, I work in a hospital with a trauma center, I have seen patients where the shooter was in the trauma unit not too far from the victim. I asked a nurse how she deals with it and she says, I just look at them as a person, I can't even think about what they did. I am here only to save his life, not be a judge
County might trump the city on this one.
Remember, ingress, egress and preemptive right of access to property. I'm sure Tenn. follows customary common law and statutory & caselaw on those subjects.
