Why do you insist on a coherent narrative in this case? Can you come up with a coherent narrative that is consistent with initial reporting and that justifies this pair's behavior?
If you cannot, then any more information may be of use in judging whether these two are racial bigots or not, but will not provide any justification for their behavior,
(Bolding and colorization mine)
Tom C. is certainly more than capable of articulating his own position, but if I may, I think you may be misunderstanding him.
In my mind, he has not, not once, attempted to JUSTIFY the Case's actions so much as he has, reasonably, posited that *something*, some factor not detailed in the media reporting, MAY go a long way towards EXPLAINING the Case's motivation/reason. Which still will not justify their actions. Tom C. has been consistent in labeling their actions as stupid, reckless, illegal, etc.
What I'm hearing him say is more analogous to, "wonder what made them go off like that" than it is to "Meh--there's gotta be more than this story than is being reported, so, I'll give them the benefit of the doubt."
Note that the Case's "reason" (if it ever even comes to light, or, can be believed IF one comes to light) isn't ultimately going to matter; there's no good reason for what they did, based on what we know so far at least. They're on the hook for this, and their motivations don't really matter.
Let's just wildly speculate that the Cases had recently heard something about fake delivery drivers robbing houses in rented vehicles made to look like FedEx trucks. And so they made a mistake, which wouldn't be entirely unreasonable, and jumped to a conclusion.
That might EXPLAIN their actions while still not JUSTIFYING them, since even if the driver WAS a fake, driving a decoy, and planning to rob their house, you can't follow them down the road shooting at them. That's a job for cops.
I note also that
if that scenario was, for discussion's sake, their true motivation, it would also neuter the (admittedly sexier) angle of racism that the media tends to want to overplay before they know all the facts. It's
possible that the Cases couldn't care less that the driver was black; their problem with him was that they thought he was posing as a FedEx driver to commit robbery.
We don't know that part, and possibly never will. Which still leaves their actions unjustified.
