David Fleshler and Megan O’Matz:

Despite an extraordinary series of governmental failures leading to the bloodshed in Parkland, just a few low-level employees have faced consequences over errors that may have cost lives.

But not the school administrators who failed to act on warnings of weak security at Marjory Stoneman Douglas High School, or the ones who mismanaged gunman Nikolas Cruz’s special education needs when he was a student there. Not the sheriff’s deputies who took cover while children were shot, or their supervisors. And, by all indications, no one at the FBI, which fumbled compelling, back-to-back tips about Cruz in the months before his rampage.

“There were so many mistakes,” said Broward County Commissioner Michael Udine, whose district includes Stoneman Douglas. “I don’t feel there’s been sufficient accountability. But more importantly, the people that live in northwest Broward, my neighbors and friends, don’t feel there’s been accountability.”

Cruz, who has confessed, clearly deserves the most blame for the Feb. 14 shooting. And the easy availability of firearms in Florida played a role in an attack in which the gunman stalked the halls with a high-capacity rifle and fired into classrooms, killing 17 and wounding 17.

But at the agencies charged with keeping Broward County’s schools safe, where leaders have been quick to pat themselves on the back for their work, few people have suffered consequences for multiple errors that have come to light since the shooting.
