Jim Geraghty of National Review and Greg Corombos of Radio America look at the possible pros and cons of President Trump meeting face-to-face with Kim Jong-Un, hoping there's a shot at progress but realizing the North Koreans have no track record of honesty.  They also fume as radio chatter from the Florida high school shooting confirms Deputy Scot Peterson knew right away that shots were being fired inside the building, a direct contradiction of his earlier explanation that he did not enter the building because he thought the shots were coming from outside.  And they celebrate a robust jobs report, with over 300,000 new jobs added in February.
