Who is more likely to be accurate, the person that is in high stress situations frequently or the person who is doing it for the first time? I'm not saying that officers are going to be 100% accurate, but I think it's entirely fair to assume their ability to recall and restate facts accurately is better than your standard eye witness because of their experience. And again, they go through training on how to remain calm, keep an eye out, survey the scene, etc. Joe Schmo doesn't. Joe Schmo just happens to see something during his everyday life experience.
Why is it fair to assume that? Repetitive stress can permanently affect your mind. I wouldn't be surprised if it makes you less reliable over time, but I'd say find out what the research says instead of blindly assuming.
