IMO, it’s been going on for years, a few “incidents” at a time, testing the waters for “Soft Targets”. Ft Hood was a “ST”, in that no one was armed, and the jihadis knew it. How many other “incidents” have been covered-up by authorities, beyond what we’ve read/heard about?
Yes, it has.
Eventually it will come to a head where the press and the liars in office won’t be able to cover it up.
If there is mercy, it will happen sooner rather than later so that a higher portion of the population can wake up quicker and be better prepared against a smaller threat rather than a later larger threat of governmental{obamunism} creation.
