They can’t come up with a narrative that both fits the facts and hides the truth...
My guess is they’ve got several different alternative narratives ready to go but the people in charge realize they just aren’t smart enough to pick the most convincing from the pile of lies they have to choose from and are paralyzed with fear and just can’t decide which narrative to “go with”.
They're working on it. Everyone connected is hunkered down, threatening everyone else to just "keep your {expletive} mouth shut" and so far it is working. The silence from the officials and officers connected is deafening. Meanwhile the coroner and a few key others are probably figuring out just what exactly their price is. I'd bet good money there are a few people who end up retiring next year, heading to a large beach house on the gulf coast with a good sized fishing boat out in the gulf...
I know that sounds cynical but... The whole setup and run-up to the incident stinks; it shouldn't take nearly this long to process 9 bodies and evidence; the complete and effective clamp down on all information smacks of serious CYA by the LEO depts involved; stories of witnesses leaking out do not correlate well with "official" statements; the entire attitude of the legal system in that neck of the woods seems high-handed and condescending. So yeah, I have serious doubts as to the honesty and integrity behind the "official" story. It just isn't adding up to a good outcome for law enforcement. I think they f'd up, big time, and are scrambling to mitigate the damage.
