The logic there is if the criminal appeals and gets a charge dropped due to a technicality or some other issue then they are still in jail. Not ideal but not without logic.
"Technicality" is a euphemism for "constitutional rights". You don't get out of prison because the cop spelled your name wrong as he booked you. You get out because, in the eyes of the system that sentenced you in the first place, someone steamrolled over rights enshrined at the heart of the American system. Those rights are meaningless if governments may violate them without repercussion. The sum of all the "technicalities" is the thing we call freedom.
I not sure where you're going with this. If someone committed 10 murders, but the turns out to have been wrongly accused for the 11th, should that be a get-out-of-jail for the other 10?
