The Senate Judiciary Committee on Wednesday approved a bill that would authorize Briarwood Presbyterian Church to employ its own police force. The bill now moves to the Alabama Senate.

A House committee has approved a similar bill, but the proposal has not yet gotten a floor vote.

The Birmingham-area congregation of 4,000 wants to create a police department to protect its church and school.

Wow... never thought this would be something that would be considered. I understand why they would want their own police force but that has to be a massive undertaking of paperwork and restrictions to just establish a police force. What laws would they be able to enforce?
