A man who walked into a Madison elementary school to make a point about security will avoid jail time. Jonathan Fitzgerald entered a no-contest plea to a charge of disorderly conduct and was found guilty. He must do 200 hours of community service, or serve 25 days in the Dane County Jail. Last February, Fitzgerald walked into a classroom at Shorewood Hills Elementary School, told teachers he was an intruder and left a piece of cardboard with the word “gun” written on it. He did the same thing at the school’s administrative office and was later arrested.
