The Blaze reports that 2 weeks ago a relative of Cruz told police they should seize his weapons.
The Miami Herald reports that a tipster called the Broward Sheriff’s Office warning them that Cruz “could be a school shooter in the making.” Deputies neglected to write up the warning in a report.
A third report was missed when two years before the shooting a deputy investigated a warning about Cruz saying he “planned to shoot up the school.” That tip was sent to the school’s resource office, and no action followed.

Let's add these incidents to the 39 visits to the Cruz home by the Broward County police and the YouTube comment reported to the FBI that was not followed up.

Either law enforcement are incompetent or this was a planned event.
