Here is the official narrative on the one shooter story

"Johnson's military training helped him to shoot and move rapidly, "triangulating" his fire with multiple rounds so that police at first feared there were several shooters."

We need to go to r/Dallas (if theres enough voaters on v/dallas then thats th obvious first option )to find out first hand where the sniper shots were made, the layout of the area where the shots were made, to find out for ourselves if this shot triangulation was possible from one man's position.

If we learned anything from Arkancide (Google it), it's that the state will go VERY FAR, even to murder us, to keep dark secrets that they hate their own citizens, to advance their agenda. The people that are there to protect our interests, paid from our taxes (now considered theft) have turned into mobsters. Our tax money turned on ourselves.

...the authorities are surprised?

Ah, every time the shooter isn't white this happens.

What? No Jews from the Southern Poverty Law Center to start making associations with Black Supremacy Groups, and label them Domestic Terrorists?

And please don't forget the guy on the street:
