“This bill targets people who will follow the umpire out into the parking lot, that sort of thing."
Athletic officials applauded the proposed bill.
"I've been on matches where officials have been threatened," Jason Palmer, a volleyball and water polo referee in Racine, told WDJT.
The Wisconsin Interscholastic Athletic Association also supports the bill, the television station reported.
Dave Anderson, the WIAA’s executive director, said in a statement that, “We are grateful for [the legislature’s] willingness to help protect and preserve these school-based activities ... which contribute to the fabric of our communities and society.”
Twenty-four states have laws specifically protecting referees, WDJT reported.
The two lawmakers hope to hold hearings on the bill in early 2020, WITI reported.
