Is what she said untrue?
The 9/11 hijackers used 4 or 5 harmless boxcutters to down 4 airliners, take down the twin towers of the World Trade Center, severly damage the Pentagon, and kill 3000 innocent people in the process.
Who is to say that pencils couldn't be used similarly by some group of deranged Islamic fanatics.
It sounds like she was excersizing free speech. Maybe you should listen. She might be on to something.
