Sheriff Scott Israel has shared several of the changes implemented by the Broward Sheriff’s Office in response to the mass shooting at Marjory Stoneman Douglas High School on Feb. 14 that left 17 dead and 17 injured, and resulted in multi-pronged litigation.

In a letter shared publicly on Wednesday, Israel informed Sheriff Bob Gualtieri, the chair of the Marjory Stoneman Douglas High School Public Safety Commission, of the various alterations made to the South Florida law enforcement agency. Although Israel’s email contained documents contrasting the BSO’s policies before and after the shooting, he singled out a number of “highlights of the reforms [the BSO] already adopted.” This included the enrollment of all BSO School Resource Officers into a week’s worth ”of active shooter, tactics, and concealed carbine carry/qualification training” as well as the opening of investigations into Sgt. Brian Miller and Deputy Edward Eason. The two officers were disciplined in November after body cam footage revealed that after arriving at Stoneman Douglas, Miller and Eason declined to enter the building where shooter Nikolas Cruz was active.
