I spent a few years as a volunteer firefighter. During that time I realized not all firemen are brave. Doesn’t matter if they are paid or volunteer. Had a paid lieutenant that was afraid of thunder. Acted fairly uncomfortable around smoke also.
Same for the people in law enforcement. Not all are brave.
True, but once there are something like 50 armed police officers on the scene you would think at least a couple of them would not be total cowards or sheep.
