All he’s doing is extending the media narrative that they need to push to back up their 2008 play with BO. Never mind having to lie to do so since this shooting had nothing to do with PP, it started elsewhere and ended at PP. There were no injuries to anyone at the PP facility. The white, Christian, crazy guy with a gun narrative must be pounded. The media have become a bunch of Goebbels competing to see who can tell the Big Lie best.
All of this requires the media to choose what most closely fits their narrative and overlook any other incident that doesn’t advance the Big Lie. Check out this event in NOLA that you likely haven’t heard about: http://www.nola.com/crime/index.ssf/2015/11/bunny_friend_shooting_new_orel.html
I think you may be right about it not having anything to do with PP. It seems like more people would have been killed or wounded if his goal was to shoot up a PP facility because he hated what was going on in there. It just doesn’t add up.
