Militant Democarts were convicted in 2008 of plotting to firebomb the RNC convention and to kidnap delegates. The story was never reported nationally.
Additionally, a turncoat in the GOP gave a Code Pink figure a ringside seat at the GOP convention where she then interrupted McCain’s acceptance speech. Expect more of the same crap this election cycle with scant attention from the partisan press.
I remember the bomb plot. One of the perps was from Austin I think.
