Most of our scrapers are written by inexperienced volunteers so this is probably still quite valuable as is. If it works, we’ll take it.
You could also raise a hand as a human data source; perhaps one day someone will be looking for jail data from these counties and you could offer up some way to contact you. I gave my contact info to the person you replied to. Use it if you want!
The software that my county uses is very poor for just seeing who got arrested. The only view is a "live roster" at the county jail, where they process all arrests. Some people are released very quickly.
I have it republishing on a very basic site with an easier way to view the arrests.
The software I'm scraping is called "Justice Solutions" (findtheinmate.com) and it looks like it was built without any knowledge of design OR usability.
They're not cleaned up and ready for release, but I could do that if it's useful to the project.
At least a few more counties in my state use the same software.
