Evidently the guy who did this was angry over the injustice of black folks being killed by cops and was actively seeking them out to perform his act of 'justice'. 

 

Story- what he says in the video referenced below is a dangerous mindset and one that will absolutely lay waste to this country as we know it if it keeps up. I fully understand anger and I know how destructive it can be all on it's own. I've dealt with anger issues my whole life. Mine is situational though- a reaction to certain things and is contained. This fellow and others like him, it comes from hate. Anger and hatred are a bad combination as we are beginning to see all too often. I know the black community is fed up with a great deal of things but this is not the way to deal with it. 

 

One website called "convoswithcosmo" says he travelled to Dallas in the wake of the killing of the police officers there.

In a 10 July video apparently posted from Dallas, he said only violence and financial pressure would bring about change: "Revenue and blood, revenue and blood, revenue and blood. Nothing else."
