This seems to be on par for this Iowa county which their ignorance sadly has painted a major target on their innocent citizens- related article:

"Dallas County Attorney Matt Schultz told KCCI: "I want to be clear that the decision to dismiss the criminal charges that resulted in this civil case against Dallas County was made by a previous County Attorney. I am putting the public on notice that if this situation arises again in the future, I will prosecute to the fullest extent of the law."

Schultz (a ‘tough on crime Republican’) is the prosecutor who filed charges when this thing happened originally, so no surprise he still defends his decision.
