@aliasalias how police treat human beings. It is not benign disregard. It is intentional.
I once represented a young guy on a violent offense. He had beat the shit out of somebody and almost killed them. Some deadly weapon was involved. Since he had already been to the pen a couple of times, I couldn't even try to negotiate for some lenient sentence.
At that time, we had assigned to the county a short, stocky, young highway patrol. He was an amateur boxer. My guy was in his late twenties, medium build, maybe 5'9.
The officer had been the one to arrest him. Apparently, he thought my guy needed to be taught some lesson.
He went into the cell, started to fight, and my guy got him down and beat him severely, breaking ribs, his arm, smashing his face, and the cop had to leave by ambulance.
The guy was never charged with assault on a peace officer. That incident was not investigated. The cop was assigned to another county.
Rarely do cops ever get held under scrutiny. Prison guards are also given blind eyes by the wardens.

#1.1 and the injustice system.
In 2004 I was in the County jail in Fort Worth, I was held without bail because the Probation dept. put a 'hold' on me and because of my medical needs I was put in the medical care wing in a cell I shared with a guy in for a Parole violation.
My cellmate, James, had a bunk that was close to the floor so he couldn't hurt himself by falling out of it during a seizure, and they were frequent,there was an emergency button on the wall but obviously it needed someone other than him to push it when a seizure happened.

My first night there I had to hit that button and while help was coming to the cell I was put in another cell where I stayed until whatever the responders did to stabilize James then I was moved back to the cell where he seemed to be peacefully asleep, at least for the next five or six hours until the whole scenario happened, only this time he was taken to the hospital.

The next afternoon James was brought back in his wheelchair, looking alert and talkative so I heard how he'd violated his parole.
He had not been home for his Parole officer's home visit and his PO promptly revoked his parole and a warrant was issued for his arrest and the warrant was served on him where they found him, at the County hospital, John Peter Smith. He got there from home via an ambulance because he'd had another seizure and a friend called them to the house. That is why he missed being home for the PO's visit.

I told him this has gotta be slam dunk for you when your PO hears the whole story, then he told me he had been there for six months and his PO had called for a hearing to review his revocation order and the date hadn't happened yet because of delays and scheduling problems.
Despite the facts about his reason for not being at home, James was still afraid he was going back to prison regardless, a place where he had spent fifteen years before parole.

James told me when I asked that he did have a pro bono lawyer, and not his first but he couldn't remember his name but it didn't matter because he'd heard it had been assigned to another one that he hoped to see someday soon.
As the days and weeks went by the seizures continued at least four or five times a week, minimum, at all hours of the day and night, I kept punching that emergency button and eventually learned that the bell ringing twice meant the in house doctor was needed, three rings meant an ambulance was needed asap. Three rings happened more than just a few times and every time after a day or maybe two days later James wold be rolled back into the cell.

I don't want to make this too long but I want to tell a few more things before I say how it ended.
James' time in that cell had not been good, to say the least, in fact his last cell mate would just take his food as James was incapable of fighting from a wheelchair or bed.
James told inmate friends about it when everyone was sent to the 'day room' to eat at noon and at five pm, but breakfast was served at the cell and one guard after hearing about it all peered thru the little window of the cell one morning after breakfast had been delivered and he witnessed the inmate taking his food.
Of course that inmate was removed, and from what I heard the guards beat him badly during the 'extraction', which I confess I was glad to hear.

I now understood why after I was first put in that cell with James I would see a guard would come to the window after the food cart had already moved on, but it stopped after a week and maybe because unknown to me James had told his inmate friends that "Ronnie and I have a good arrangement".
What James and I both liked was the fact that I'm a vegetarian, so I traded meat for his veggies. I help him on other things but getting the meat for non meat items was the big deal and maybe it explains why an older Black man, like James,started getting his newspaper sent to me after he and his cell mate were finished with it, even sending along a package of coffee one time (he wouldn't know I've never been a coffee drinker but James certainly was) so everyone was a winner.

How it ended.
Every Wednesday a Preacher would come to the floor for a sermon out in the hallway and most of the others ,like myself, only attended just to get out of the cell for a couple of hours because in that unit you were in lock down around the clock with the exception a short time for two of the meals and once a week a few hours in the day room.
Then one day James told me the Church of that Pastor had taken up his cause with the pro bono help of two members of the Church's congregation and it was looking good.
James was happy, to say the least,and I was happy for him when I heard he was being released after a bunch of paperwork was ready later in the day but before that happened another seizure happened and as I was moved to another cell so they could get in there and work on James I heard the bell ring three times so I knew he was going to the hospital.
The way I saw it at least he wouldn't be brought back to jail when he was released. That felt good.

The next evening I asked a couple of guards if James was coming back to jail because every time I heard the door buzzer I worried they'd be wheeling James back. Those guards glared at me, and gave me that 'I'd better shut up' feeling, so I said nothing else.
But in the jail pipeline others knew the answer and the inmate that had been giving me his newspaper told me in the day room that James had died of a heart attack downstairs.

That story bothers the hell out of me every time I think about it.

@WaterLily but it appears it will not be announced ahead of time.
From the timeline all the sources have given, it should be happening by Sunday or Monday.
I would imagine the announcement would come when people are most likely to be home.

#2.1 Will we have 12 hours' warning (or at least a few)?

I have no doubt this is coming. Just wondering about when to head to the store for the last time, in anticipation.
