Maybe you got a smart one.
"A 2010 Michigan State University study found that cops with a two or four-year degree resorted to using force 56 percent of the time, while those with only a GED or high school diploma used force 68 percent of the time. The Bureau of Justice Statistics found in 2003 that 83 percent of U.S. police agencies require cops only to have a GED or high school diploma, and only one percent require a four-year college degree."

Not many people are going to spend tens of thousands of dollars to get a degree in order to get a job which pays as poorly as law enforcement.
Not shown in the statistics are a breakdown of the demographics. Law enforcement officers with lower levels of education are more likely to work in high-crime areas than those with higher educations. Those few officers with degrees tend to work as detectives, adminsitrators, and specialists, and are less likely to deal with physical arrests.
Law enforcement is not the most pleasant occupation. Police officers are seldom welcomed whenever they deal with the public. Their work involves dealing with the worst of people at the worst of times. Traffic stops, accidents, robberies, fights, and worse. When dealing with officers who see the worst things which people can do on a regular basis, and who for their own protection have to assume the worst-case scenario in every situation, it is best to be non-confrontational. Poking an angry dog with a stick is likely to result in your getting bitten, and after years of dealing with the worst which humanity has to offer, police officers are easily angered.
I worked in law enforcement myself for some time, and have been photographed and videotaped on several occasions. One time that I recall was a kid (a 17 year old black kid, 6 feet tall) who ran after being pulled over in a stolen car. He had been arrested several times for stealing cars since he was 13. He had also been arrested a few times for drug dealing and possession, evading arrest, and burglary, a real class act. He was also the father of three children by three different women, one of these women he had beaten nearly to death in an argument. The last time he was arrested, he bolted from the scene, and was tackled a short distance away. A bystander started screaming that we were abusing the young car thief, and began recording the arrest with her cell phone, screaming that she would give the video to "help me Howard". She was leaning over us, screaming and carrying on, and honestly, it was a little hard to get the kid in cuffs with all this going on. She then starting kicking another officer, and ended up going to jail as well. In the young man's pants we found a gun, and a bag of crack rocks. It turned out the gun had been used in a couple of previous shootings in the area.
Stories like this were a daily occurrence, and working in this kind of environment does not make police officers very soft or kind-hearted. I have been pulled over by other officers in other jurisdictions, and seen them come up slowly behind my car with their guns drawn. I stay calm and do what I am asked; I know how intense a traffic stop can be, and how impossible it is to predict what people do. You always have to assume the worst thing may happen. In this situation, if the person being stopped does something unexpected, it is better to act quickly and, if necessary, physically, for everyone's safety. Many police have been killed and injured during traffic stops, and as it generally happens when least expected, you must always expect it.
