My oldest son is a police officer. One early Sunday morning while doing a ride along there was a shooting all the way across town. We headed there immediately via an expressway with lights every 1/4 mile or so. With siren and lights blaring in between the lights we were hitting close to 100 mph, only to slow to 30 or so going through the intersections. Over and over, over and over. At the time the PD had Crown Vics. I couldn't believe the braking power those "cop brakes" had. Zero fade and no vibrations during or after. When we raced to the scene and stopped the front brakes were smoking so badly it was like the entire front of the car was on fire.
And seeing your son race up the stairs with his AR in hand and run into a low rent apartment complex where gun fire was taking place was rather nerve wracking too. After doing three ride alongs and seeing nearly nonstop action - including a suicide by hanging in a storage locker - it made me realize that society is teetering on the brink of total chaos. I don't know how my son maintains his sanity seeing this day in and day out.
Anyway, whatever they were, those cop brakes were the real deal.
