Check out the video links.  At least one of those was a DUI arrest.  Your challenge was "Cite one instance... damaging the perp's car" that has been used during a DUI stop."  

The P.I.T. maneuver is used to "stop" a "perp's car.  If he is being stopped and arrested for DUI, I view that as "during a stop" and usually, as shown in the videos, causes damage to his car.

Semantics?  Hair splitting?  Or just ego involvement because you made an overbroad statement which I just called you on?
