Armed Protection - Politicians or School Kids

A question keeps nagging me that begs for an answer.

Why do liberal Democrat politicians have tax payer funded armed security protection, yet want to deny school teachers and kids the protection of armed security?  I can't believe that any "crazy" intent on shooting up a classroom of kids would attempt such an act in the presence of an armed security officer.  They may be crazy, but they're not stupid.

Near as I can determine the high profile politicians, celebrities, movie actors, entertainers, et al that speak so vehemently against guns all have armed security guards accompany them every where they go.  We have armed guards protecting money in banks and armored cars, and elsewhere.  So, why are the liberals and their ilk so ferociously against guns in the hands of responsible citizens trained and licensed to posses a firearm, and especially against armed security protection for our most precious possessions, our kids?  Go figure!

As Wayne LaPierre of the NRA said, "The way to stop a bad man with a gun is a good man with a gun."
