I once taught a block on 4th amendment issues in a course titled "Policing in America" and the professor shared the recording of it with a law professor colleague of his who invited me to give the same lecture to his students.
It was a lively discussion and many of them became quite angry at first and then learned a lot about perception, the importance of phrasing, and SCOTUS case law.
I infuriated many with my explanations of how LEO gain consent to search etc. They enjoyed it in the end.
I allow students in any course I'm teaching to interrupt me with questions at any time. It has never been an issue during any other course I've taught to LE. That is not a wise strategy when lecturing a lot of liberal law students on the finer points of police procedure however.
