A bill headed to the governor’s desk would bar civilian oversight boards from investigating instances of police misconduct, further restricting their limited powers of accountability.

The Florida legislature approved a bill this month that would further limit local civilian police oversight boards by barring them from investigating allegations of police misconduct. Police unions support the bill as a measure to protect the rights of officers, though critics say it represents yet another blow to police accountability efforts already shackled by existing state laws giving cops extraordinary legal protections.
