If at every instant in it’s flight an arrow has a distinct and measurable position, when does it move?
The answer is, of course, that it’s an object in motion and so has a quality of change that you are ignoring when you merely measure the position. This is why God, Liebniz, and Newton invented Calculus.
Thus I am skeptical of these “frame by frame” video deconstructions that show every instance of police murder is justified. They ignore the change that is the undisputed fact less than 2 seconds after getting out of the car, rookie patrolman Timothy Loehmann shot 12 year old Tamir Rice dead.
Cleveland prosecutor releases analysis of Tamir Rice surveillance footage

The family’s experts said bad police tactics led to Tamir’s death. Roger Carr, a consultant from Santee, California, noted in his report that Garmback, Loehmann’s training officer, should have stopped the cruiser a distance away from Tamir to give the officers time to assess the situation.
“The officers created the alleged danger here,” Carr wrote in his report.
Carr criticized the prosecutors’ experts for assuming that Loehmann warned Tamir to raise his hands before he shot him, which a Cleveland deputy chief told reporters shortly after the shooting. Investigators from the Cuyahoga County sheriff’s office noted in a report that there was no evidence Loehmann shouted anything.
