They film crew did not start taking video when the police started spraying, the video was cut to create the greatest impact on the viewing
audience. What you do not see are the events leading up to the spray.

I believe you are correct on the order of the application of force, but the video does not show the fights, the drug sales, the looting and
vandalism. The video does not show the remaining conditions of the premises when the demonstrators left. It may be a construction site,
but it is private property.

The owner of the property can still be held liable for injuries caused by the vandals if the owner did nothing to stop the activities.
