They built a flyway from the jail area to the courtroom in my piddly little Oregon county. Three floors up, no exposure. I was struck by how nearly identical this courtroom was to ours (right down to the sad-sack female prosecuting attorney ). Same decorator. I suppose.
That presents a problem most people would not have the expertise or the persistence to overcome. Plus big risk of hurting innocents dealing with something like that. I suppose they could bribe another inmate to act on their behalf
