Something seriously big time must be going on behind the scenes for all these mass shootings consecutively. Operators must be hammering the hell out of them behind the scenes and they are countering by launching these things to try to induce panic.
Very few people care about these shootings. I was on social media earlier and nobody was talking about it (at all). The only people pushing it and talking about it are the same people that always do, very few care about them because they are focused on their own lives or on getting rid of what they consider to be harming the country and the lines have been drawn long ago/aren't changing. At this point very few will pay attention to these shootings beyond "was it fake?" or "what race was the person?" and even those are few.
