Just hours after the carnage at Newtown, Conn., President Barack Obama spoke with raw emotion of the need for action to prevent more tragedies like the December massacre of 20 schoolchildren and six adults at Sandy Hook Elementary.

The hard-fought politics of gun control guarantee that a long, tortuous legislative journey lies ahead. One proposal that’s not even on the table: the National Rifle Association’s call for every school to have armed guards. Plenty of school districts already do that on their own, though.
