The big problem with this whole «incident» should be fairly obvious. The attack happened on the range (hallway of cells) directly below the one where I am celled, so I'm not personally familiar with the prisoners down there, though the prisoner who got stabbed is a «co-defendant» (crime partner of one of the prisoners on my range who I am familiar with (and get along with). The «word» is that the prisoner who got stabbed had complained several times about the other prisoner threatening him (i.e. he is a «rat»). So, the odds that the other prisoner's door got opened by «accident» just as the rat was being escorted past, is slim; and the fact that the attacked appeared to be ready for the «accident» to happen, with home-made knife (shank) in hand, ready to attack as soon when his door opened, is a pretty good indication that he wasn't the only one who wanted to hurt the rat.
The guard who «accidentally» opened the wrong door, and more than likely the guard who ended up getting stabbed while escorting the rat, had to be in on the attack. They probably told the prisoner to be ready for his door to open «accidetally» (this kind of «information exchange» happens often between guards and the prisoners they are «familiar» with – all sorts of rules are in place that are meant to prevent it, but it is one of those «human nature» things that no amount of rules or laws will ever stop). One of the guards could have simply whispered in the prisoner's cell, «Hey, if your door opens accidentally when the rat comes back from rec, don't do anything 'stupid'», which of course means, «Be ready».
The guards probably thought they were being «cool», and having some «fun» at the same time (a lot of guards thrive on violence even more than the prisoners – so they create situations like this so they can «do their job», and look like heroes, I suppose). But, I doubt if they expeted their patsy to come out of the cell armed with a shank! So the whole thing backfired, and even got the guard who was escorting the rat stabbed as he tried to «restrain» the attacker (this guard may or may not have been «in» on the «fun» - but the guard who «accidentally» opened the wrong door was definitely «in» on it).
So now changes are coming. The «rules» have failed once again (as they always do eventually), so now more rules will have to be made (the rulemakers – i.e. pharisees – never seem to realize that the rules never actually «fail», they just never work in the first place, and only appear to work at all by sheer chance, until the next «incident» occurs and more rules «need» to be made). The «up shot» is that all the other prisoners on death row will now loose more «privileges» and suffer more restrictions (i.e. «security measures») as a result (the new «rules» invariably only end up «punishing» the prisoners who had nothing to do with what happened). They've already assigned two fulltime lieutenants (one for day shift and one for swing) to the SCU, which is a small unit that never needed its own Lts before now. So, unless the new Lts plan on twiddling their thumbs all day and getting paid for it, they're most likely going to create some excitement of their own, to make themselves feel like «heroes» (i.e. useful) too. And that's not good for the prisoners... it never is. (As I heard the rat's co-defendant say – who himself is a solid convict as far as I'm concerned - «Shit rolls downhill, and we're at the bottom of the hill!»)

P.S. It may be interesting to note that the SCU (death row) unit is considered the most «secure» unit in a Federal «Super Max» (Maximum Security) prison. If government «officials» can't keep even one small unit secure in prison, then how can they keep the nation secure? They can't, never could, never will, but will always pretend they can, and take trillions of dollars to maintain their facade, and propaganda. «They» are the ones paid to be «heroes». (Paying someone to be a hero is like paying someone to be your lover; it's just a form of prostitution.)
Disclaimer: It should be obvious, I hope, that much of the information I've provided here is hearsay and not reliable. It is, however, the best information I have at this time, considerating that the B.O.P. is not in the habit of publishing news reports when «incidents» like this happen (and when they do ultimately decide to release information for public consumption, you can be sure it is not the whole story – so I hope I'll be excused for attempting to provide another «version» of the truth).
