News organizations including The Associated Press are seeking additional, external surveillance video footage that depicts the law enforcement response to the shooting at Stoneman Douglas that killed 17 people in February.
A motion filed on Wednesday asks a Broward County judge to determine how much video exists and whether it should be released.
The motion says there were about 70 surveillance cameras at the high school when the massacre took place Feb. 14 and many appear to show the actions of police officers and deputies.
