Don't worry about it.
In my state all of the Troopers are trained at the advanced level. It's not really that hard. Then their are those of us that are trained to the Technical Investigator and Reconstructionist level. Those are voluntary and were in charge of handling fatality's and serious injury collisions.
Some states also use crash teams for fatality's. So on that team you might have one person that is really good at the scene work, another that is good with interviews, and another that is a math genius who does all the calculations.
Excuse me Officer, I have a stupid Question. "No problem, I've got a stupid answer for you!"
