Summary: The Supreme Court ruled that cases about police-involved shootings must factor in everything that happened up to the point of the shooting instead of just the 'moment of threat' as was the case before (Barnes vs. Felix). Five 'factors' you need to know when carrying: 1. The severity of the offense. Cops can use more force against you the more serious the crime is. 2. Did you pose an "immediate threat" to the officer? The officer is held to the 'reasonable belief' standard. 3. Resistance or evasion. Resisting or fleeing from an arrest gives the officer a reason to use increased force. 4. The officer's conduct and warnings. Officers are required to attempt to deescalate before resorting to use of force. 5. Proportionality and viable alternatives. Did the officer use too much force and/or resort to force without trying alternatives first. That's my non-lawyer take on the video. Your mileage may vary.
