Fort Atkinson would be an interesting place. Two years ago the Chief of Police wrote to an OCDO member:
"Our stance on the disorderly conduct statute has not changed, and I will again attempt to outline our understanding of the law.
After receiving your second letter, I discussed it with Jefferson County District Attorney David Wambach. District Attorney Wambach echoed my interpretation of the disorderly conduct statute and even shared with me the fact the statute does not require an actual complaint, only that the conduct tends to cause a disturbance.
Disorderly conduct does not necessarily require disruptions that implicate the public directly. This section encompasses conduct that tends to cause a disturbance or disruption that is personal or private in nature, as long as there exists the real possibility that the disturbance or disruption will spill over and disrupt the peace, order, or safety of the surrounding community as well.
With the above in mind, I again remind you that an arrest for disorderly conduct would be likely if a person were to go armed with a firearm."
I then exchanged a couple of letters with the Jefferson County District Attorney and he completely concurred with the chief's stance. There's a new DA there now, but Chief Brus is still in Ft. Atkinson. It would be very interesting to see whether his opinion on open carry has changed over the course of the past two years.
