But there are really two things here.

(1) Are the cyclists creating a hazard? Sounds like possibly yes.

(2) Does the hazard created by the cyclists rise to the level that police officers are authorized to use DEADLY FORCE to stop them? Uh, no.

Shooting out a car's tires is considered deadly force. Running a motorcycle off the road, same thing. Intentionally causing a bicyclist to crash at high speed - that's deadly force too.

Sure the cyclists need to cool it. But this is basically the same scenario as a cop shooting a shoplifter. Wrong, wrong, wrong.
