They're hoping that AQ will take the path of least resistance by announcing their intent to run interference. It may be an attempt to protect the DNC convention by sacrificing the lives of nonspecific casualties.
They may also, if incited, go so far as to admit their desire for specific casualties.
They are traitorous, treasonous scum and should be treated as enemy combatants the very moment they attempt any of what they are recommending.
If the government doesn't take a no tolerance/gloves off position on this now, we may have a serious problem.
I'm guessing most if not all of these groups of home grown crazies have been penetrated over the years. The Feds are pretty good at this sort of thing and these folks aren't for the most part, that bright, or even trained (at least in tradecraft). Although some may have some military background. However these whackos must not be underestimated in any way. That could be fatal, so I would agree with you that harsh consequences should result from any sort of action on their part.
