The average driver isn't trained as a defensive driver. Rottncop was running code (lights and siren), had a person actually pull into an intersection, and STOPPED. RC saw him, managed to manuever his car hard to the side, jumped the curb, and bring his own car to a stand after flying though the air over the median. RC described his thought processes, to avoid hitting the other car, which surely would have killed one or even both. The other driver just took off, but not without being seen by the second trooper heading for the same code call. Lucky for the dumbo who stopped mid intersection, the second cop was watching RC and couldn't identify him....but the guy just froze. Lucky for RC he is a trained professional driver, REQUIRED to take defensive driving courses every few weeks, and to AVOID things like that. These courses are extreme driving to the max. Unbelieveable what they can make a car do. Like stunt drivers. Teens certainly should NOT be driving excessive rates of speed, their brains aren't developed nearly enough to react in time to avoid killing themselves or someone else if something appears out of nowhere. Heck many adults can't do it.
There is always an internal investigation when a trooper is involved in an accident. ALWAYS and not every trooper comes away clean. It's a difficult process. Much like if a trooper's wife has an injury, like i had, smashing my face, he is investigated as well and this investigation never "really" closes. So there ARE controls in place, at least at the state level.
