There's a long cut, and the camera zooms in on them before the shots. It's pretty easy to spot that there's context that is missing.
It's probably 50-50 if that context would change anything in reality, but the fact it's missing could mean anything from the cameraman just getting more background footage to the group putting away their firearms after taking potshots at soldiers. Most likely, it's somewhere in between all that and they were warned verbally to turn around.
Don't underestimate people who have a vested interest in one side of a story and are willing to sacrifice anything to push that agenda.
That and the danger that a group will take their status and abuse it to push a particular agenda despite evidence to the contrary. At that point they're not fact checking - they're actively pushing disinformation.
