I agree that these failed policies suck, and we shouldn't demo buildings in general. If we have a plan implemented with $$ set aside, then maybe, just maybe, a demo (RARELY) could work.
BUT, in the case of the courthouse, a building which I've spent many, many hours in, I can't envision COJ doing anything to it that would constitute adaptive reuse. I'm not even sure a private company could do it. I don't think the city, the banks, private industry (in this town at least) has the drive for another John Gorrie-esque rehab project.
I say this thing gets torn down within the next 5 years. Hopefully, just hopefully, we have a plan, and money in place to fix whats left.
