So according to you, 84 year olds get a lot of late night visitors, or is this some conspiracy where he really invited the guy over to shoot him and everyone is lying to cover up the trap? Not sure what you're arguing, but we already know he wasn't expecting visitors and was already in bed, and nobody is even disputing that.
Not sure which case you're claiming is "no questions asked", but it isn't this one. This one he was taken into custody, questioned and later charged with felonies. so there were quite a lot of "questions asked", including of the neighbors who also said it was odd when he heard a car pull up to the elderly neighbor's house late at night.
And here's the crime map of the neighborhood with 3 burglaries, about 20 assaults and about 20 thefts just in the last couple months within about half a mile of where this happened.
