Kentucky's House Judiciary Committee approved the most sweeping changes to the state's penal code in a generation in an effort to reduce prison and jail crowding. The committee voted unanimously to send House Bill 463 to the full House, where a floor vote is expected tomorrow. The result of much negotiation and compromise, the bill would steer many drug addicts into treatment and community supervision rather than prison. It drew praise from prosecutors, defense lawyers, judges and local leaders. The Kentucky Chamber of Commerce endorsed it, warning that the state's incarceration costs are draining resources that could better be spent on education.
