I know this was actually done in 2018 in Chicago with a sneaker truck as a bait trap.
Seeing a lot of reports almost unbelievable (whether info or disinformation) about forces of further provocation at work—beyond organic protestors.
Alleged palette of bricks suspected of being intentionally placed as trap—tonincite violence.
To arm protestors to do damage outside a court house, create further public spectacle, shift popular opinion mindset away from "Justice" to "punish crazed rioters"
