If you are not aware, do some reading. Guy named Stephen Paddock is the dead terrorist, killed by responding LV Metro LEO's. I have little doubt that it will come out in the next few days/weeks that he was an alt-left/anti-fa/bernie-type loving sociopath.
We will continue to stand united, we will continue to fight terrorism regardless of where it comes from and what its ideals are, make sure your level of readiness is turned up, these things rarely come in solo events.
