Florida became the first state with a law that spells out that prosecutors, and not defendants, have the burden of proof in pretrial “stand your ground” hearings when Republican Gov. Rick Scott signed a bill Friday.

The measure was among 16 bills that Scott signed, including a bill that gives students and school employees a broader right to express their religious viewpoint in schools.

The “stand your ground” bill was fought by prosecutors who say it will make their job more difficult to convict people who commit acts of violence and claim self-defense.
