Too much propaganda on this one. Three people not black, not Hispanic, one an ugly looking woman with light skin, could all very well be described as three white males. That does not look like a conspiracy to me.
While searching it all out I did see a twitter account of a young man with black lives matter pumping up the conspiracy angle with an alleged report of 'three white males' and a comment concerning a police drill.
So I looked into the drill conspiracy theory; Orange County fairgrounds is just around the corner from where the shooting took place. Spent a lot of time down near there in my youth as my grandmother owned property on Waterman, an aunt lived across the wash there also.
Here is what I noticed about a young man in the photo on twitter with that three males report and a timely drill taking place as the shooting was going down. He has a looks about him that reminds me of my own nephew a lot. My first thoughts when reading his comments was he has a look about him just like the nephew and seems as though he possibly has an attitude like my nephew. A bit of a smart ass with a "My mother was a street prostitute, my dad doesn't care and the world owes me" flare to it and laughs at stirring a pot of shit.
