They couldn't sue InTouch and their employees without sueing the City of Springdale and all the individuals involved with the redacting process. It would have looked reeeeally bad had they only gunned for InTouch/Bauer Media. There were several individuals involved and the City of Springdale before it was whittled down to these three. The case against Springdale as a city was always going to be dismissed. There is some clause in Arkansas law about that. It was then a case of who was involved in the redacting process that could be held responsible for not properly redacting the information. Now it is down to these three people.
Realistically I would have rather see them campaign for more strigent privacy laws and mandatory, comprehensive FOIA education for government employees. I will reiterate I am skeptical that there will be any meaningful change that comes out of the remainder of this lawsuit. It doesn't harm the city, county, or state in any shape or form. They have no initiative to change. Now it's just three meaningless individuals who were befuddled on how to handle such a request. No taxpayer money will be lost to the Duggars as a result. All the ones who had the power to change laws have had the lawsuits dismissed against them.
It'll probably take happening to a bigger celebrity for such laws to actually change.
