Do a quick search - look at the video's. Two of the most dangerous circumstances for police are domestic violence calls and traffic stops.
The Hazards of Traffic Stops
Conducted with everything from sunny smiles to shows of force, thousands of traffic stops take place daily across America's highways and byways. These detentions are effected by officers whose tactics are often sounder than those of their predecessors and whose patrol vehicles sport state-of-the-art safety features. Yet the traffic stop remains one of the most dangerous aspects of police work.
Ever wonder why police touch the drivers rear brake light?
Originally, another reason why cops touch tail lights was to leave their fingerprints on the vehicle. In case the officer found himself in a dangerous situation while pulling over the subject vehicle, fingerprint evidence would prove that he or she was present at the scene. The fingerprints would only be utilized if the interaction between the driver and the cop led to a criminal investigation, like a car accident or shooting. However, this isn’t always a sure-fire way to help an investigation some since the fingerprints can be smudged or tampered with, as well as washed away by rain or snow.
More often than not, there are better ways for police to obtain evidence from a vehicular crime scene than the fingerprints on the car.
