it is a theater group. Might even be a new show on ABC's fall lineup going thru a pilot now.
it is totally normal to shoot a fully automatic handgun and no smoke or damage to anything you are shooting at is visible.. I think the antifa-ggits are playing gunshot noises over a very close speaker. The shooter gets out of the car threatening with his weapon.
same setup as when heather the whale died on the sidewalk from her pulse going over 60 when the assburgers kid was fleeing from the same group pointing rifles at him in charlottesville NC.
