In my first post to this thread I believe I came down on the neighbor even used a medium non-nice adjective. I wish to backpedal HARD on that. I read in the NYT they released the call she made and she couldn't have been more precise. She said clearly that the people gaining entry could be homeowners, she wasn't sure. She did not refer to race of her own volition, the dispatcher asked her for more information.
I now am inclined to believe the caller was an ideal neighbor and did absolutely nothing to be critical of. I retract anything in the least critical about her.
