This is mildly amusing and a take on LEOs in class. Years ago one of my grad psych professors was going the run the famous eye witness experiment in his night psych class. A grad student would run in and shoot him with a starter pistol and run out. The shooter would curse him and then go bang. Then the prof would fall and then jump up. The class would write down what they saw.
However, half the class was Buffalo cops. Nice guys - met from my class in the middle of a blizzard.
Anyone, we debated telling the prof. We grad students didn't really like the shooter - so it gave us pause. But we did the right thing and the experiment was aborted. The wave of SW Model 10s opening up would have been a hoot (sorry to say).
