The cops at Parkland couldn't even establish a proper perimeter around the crime scene. After the killer was done running amok he wandered off, got himself a slurpee out of Subway and then had breakfast at McDonalds. They did not even try and identify who was responsible for the shooting.
Oh, and even after the shooter had been taken into custody the sheriff still denied access to the scene to emergency medical personnel.
There can't be an excuse for that degree of malicious incompetence but the courts gave them one anyway.
