How can you have hours of discussion at a government-sponsored conference on school safety that wouldn't have happened without a number of recent high profile, often deadly, school shootings-- the most recent a 13 year old firing an AK47 at a Joplin, MO middle school-- and no one save a few questioners is willing to directly broach the subject of gun violence in schools?  Evidently its pretty easy.  For example, according to Dana Milbank, the President, his Education Secretary and the Attorney General made it through several hours of panel discussion without once saying the word "guns".
