I'm ambivalent and right-leaning. The reason is because too many people are railroaded in by two collaborating witnesses and their supporters who may have committed the crime themselves. In Illinois, there is a "Project Innocence" that found that 11 prisoners on death row in Illinois did not commit the crimes for which they were sentenced to death. It caused a governor to suspend the death penalty in his state until he fulfilled his term.
When I first learned of the Innocence Project, I became anti-death penalty, but as time wore on, I saw that there are some who should never, never be allowed to see daylight again. This would happen in the event of a natural catastrophe such as a flood or earthquake on prison grounds. The evacuation could result in the escape of a serial killer who would just continue his crime. Maybe the public would be served if this type of criminal was disabled from hurting others for good.
The Innocence Project
The problem with your hypothetical is that it hasn't happened - whereas hundreds of innocent people have been executed unjustly.
The odds of someone escaping a SuperMax facility are lower than the odds of a lethal injection not working.
The trouble with your analysis is that there wasn't one made by you.
Here's one who escaped while being transported.
Here are 450 who escaped through a tunnel. 100 of them were Taliban commanders
4,000 prisoners escaped in Haiti in the hurricane/tsunami that hit there in 2010
A Mass Murderer Escapes from Jail
In the Afghanistan break, a number of those people may have made it to this country, where they would likely go underground as part of a cell of our nation's most dangerous enemies.
Haiti is not that far from our country either.
The mass murderer who escaped in Srikakulam likely would have left his country and gone someplace else, too.
There goes your theory that nothing can go wrong that could bring a mass murderer into the population of our nation.
Even so, theDoctorsIn, I respect your opinion. I'm still maintaining my ambivalent attitude because I just don't trust the system, and I don't trust the criminally incarcerated mass murderers who eluded authorities sometimes for 3 or 4 decades. Their lives are built around elusive maneuvers including moving every 3 or 4 hours, days, or months, never more than a year anywhere, disappearing as quietly as the day they arrived in someone's community, doing who know how many repeat crimes.
