Not even meming or “even if he did it, let him walk” (yes, but let’s ignore that for a moment) I still personally consider this incredibly likely.

The timing feels suspect for catching him at all. Given how “professional” the actions in the video are, I don’t think it makes sense that the perpetrator would still have the weapon actively on them that long after. You’re really telling me the person who did what’s in the video wouldn’t find a moment to dump the gun in a storm drain, dumpster, etc? Especially in all the time they weren’t caught?
