Until the officer aims too far to one side and whacks the perp's shins with an end. What is it the trainers always say? If it doesnt work outside the dojo at full speed its not workable? How many rioters will stand in one place with their arms crossed for you to shoot them and wrap them up?
It's not for rioters, specifically. However, the majority of idiots during a disturbance actually present a pretty easy target. They are up in the police's face strutting and yelling, not going "full sprint" at the police. Obviously a full sprint charge calls for a different response, but how common are those?
This is more common than any "full sprint" nonsense.
