Proposed laws to protect whistle blowers and to make stealing public funds more difficult will be introduced in the General Assembly next year. Audits during the past five years have uncovered 250 cases of government corruption, including more than 150 cases in which the state is still trying to recover more than 10 million dollars. In one case, a former southern Indiana school superintendent owes more than $600,000. The proposed legislation also will require government employees to purchase bonds and insurance policies that can be used to recover missing funds.
