He didn't load it, but not even I, who desperately want to see Richie behind bars, would vote to convict him of falsely stating that 'it looks like' he's loading it. At the time Richie said that, he was holding the gun up as if he were inspecting or manipulating the action.
To me, he just looks like he's standing by the pet toy display, acting bored, but I already know he's just killing time before taking an open box A*I*R*17 to checkout.
The 9-1-1 operator, and this seems unfortunately typical, quickly escalated Richie's "looks like he's loading it" to "he's loading it".
When I see him just holding it pointed at the floor, or moving it up and resting it over his shoulder(8:24 in the video), I don't think "he's just looking around, waving it, waving it around" is accurate. (but it's a whole lot less embellished than a badged witness would have said)
And Richie did refuse to confirm that Crawford loaded it: "(long pause) well, it looked like he was trying to load it, I don't know" should have dialed the operator's emotional setting back from 'active shooter' to 'possible situation'.
OK, the probable cause in the video: at 8:25:30, an adult and two kids walk by as he raises it from down at his side pointed at the floor to over his shoulder pointed at the wall. "My name is Ronald Richie, he just pointed it at like two children". The question is, was that malicious, or are Richie's panties twisted so tight by now that they're cutting off the flow of oxygen to his brain and he really thought he saw that?
