The debate concerning religious expression in Bulloch County public schools could soon enter the courts. The Liberty Institute, a nonprofit law firm based in Plano, Texas, which says it is "dedicated to defending and restoring religious liberty across America," sent notice to the Bulloch County Board of Education Thursday evening that it could file suit if the school system does not, within 10 days, "put a stop to censoring the email signatures of the teachers and staff of Bulloch County Schools." Although that was not plainly stated in a letter to the school board, attorney Jeremiah G. Dys, who wrote the statement, confirmed Friday that a federal lawsuit is an option.
