Florida Failures Abound, French Defends Assault Weapons, Greitens Indicted

David French of National Review and Greg Corombos of Radio America react to the horrific news that the armed sheriff's deputy assigned to Marjorie Stoneman Douglas High School was aware of the shooter and never went in to confront him.  They also recoil at reports the sheriff's office was specifically warned in November that the shooter would do this and that his own family asked the sheriff's office to take his guns away.  David details his latest column, explaining how law-abiding Americans should have access to so-called "assault weapons" in order to match the firepower of criminals and because our founders actually did intend it to be this way.  And they discuss the political freefall of now-indicted Republican Missouri Gov. Eric Greitens, who is facing charges of invasion of privacy in connection with an extramarital affair with his hairdresser before running for governor.
