David French of National Review and Greg Corombos of Radio America wade through the details of another horrific school shooting.  This time 17 people are dead at a high school in Florida.  They honor the heroes who saved students' lives, including a football coach who died shielding kids from the gunfire.  They're also frustrated that warning signs about this shooter were abundant, including expulsion and a ban from campus, yet little was done by law enforcement to address the problem.  And they discuss the tiresome Twitter rage in the wake of tragedies like this, with David pointing out that Twitter often proves that the supposed experts on an issue are actually quite clueless in their supposed area of expertise.
