I need an assist! UPDATE!

WHAT was that word?!?!?  This is one of those niggling things that keep me awake at night!  A few months ago, I was listening in to the Thom Hartmann show when he was discussing the aftermath of the Giffords shooting.  He threw out a particular term that described the ages old and insidious practice of politicians using violent rhetoric and symbology(cough, PALIN, cough) in the hopes of "activating" TEH CRAZY in violent leaning people.  Does anyone know what the term for this is?!?!?  AAAARRG!! It's on the tip of tongue.....

Thanks in advance for any help!!!!!

Update:
STOCHASTIC TERRORISM!!!!!!   That's IT!!!  GIGI, Wavelength and Colleen!  THANK YOU!!!!
