The guy shooting the video is under investigation, as I understand it. Whether he has the formal status of "suspect" I don't know. Part of that equation is whether the guy shooting the video cooperated with local officials . . .
. . . the fact that this question is being raised might imply that the guy shooting the video was along for a joy ride in connection with the guys with the guns, but in a different vehicle. If that's the case, then you might have a situation where the three of them conspired to do some vigilantism, video it, and get some looks and likes when they post it on a channel that caters to such stuff . . .
. . . ugh.
