Trace Evidence: The Case Files of Dr. Henry Lee

Much like any professional, doctor Lee's methods have been questioned from time to time and some claim that hes not nearly as good as his show would lead you to believe. However, the show still makes for interesting television if you are into true crime. My biggest question is how does a man that works for the Connecticut state police seem to consistently be working for every other department in the entire United States? This might make sense if he were with the FBI or some other national bureau, but since he works for a state institution I don't understand how he is constantly being flown around the country to solve other crimes.
