This guy was military(?) and a gun advocate and it looks like these were legally owned weapons. Is everyone sure he's not a PAFOA member?

Additionally, apparently during the interview this morning with the guys friend( I am hearing this second hand from a friend) that there was something about this man fearing his guns would be taken from him by obama..... if so that may have something to do with the shootout, but i am not sure of any of this. Anyone watch that interview?
