Appearing on MSNBC Wednesday, Philadelphia Mayor Michael Nutter called the National Rifle Association’s suggestion of arming school officials to prevent future massacres a “completely dumbass idea.”

Filling in for host Andrea Mitchell, Luke Russert began by saying that many are calling for stricter gun laws following the deadly Newtown, Conn. shooting.

“There is a worry amongst some folks that once time passes, once we get past the State of the Union, that this could fizzle out,” Russert said.
