I've worked with a few police officers who've been injured on duty and come to our clinic. Every single one of them has told me that traffic stops (pulling over a car) are the most dangerous part of their job. You never know what that driver is going to do or what is happening in that car.
These men and women are great fun to treat and nice people. It has really made me think of the attitude and manner they have to "put on" when they are working, if only to protect themselves from (and pre-empt) the people they encounter. It must be like putting on part of their uniform.
