August Vollmer was a man who developed police professionalism. In 1905, he became a town marshal in Berkley, California. In a world with police corruption, he tried to maintain the practice of professionalism. Vollmer commanded a group of three deputies. His first task was to expand his group, so he went from three officers to twelve officers. In doing this, it allowed for a day and a night shift. Vollmer was the first chief to send his men to patrol the areas on bicycles. It made it a lot easier for officers to respond, as opposed to responding to a call on foot.
While arresting criminals, Vollmer began to question them and trying to figure out how and why the crime was made. He realized that they all used their own different methods of operation. This is known as modus operandi. Aside from this, he also made a connection between crime and scientific knowledge. He figured this out while he was investigating a suicide, in which he thought it was a homicide. By 1917, Vollmer had his whole police force operating out of cars. Berkley police department was the only department in the whole country to be operating mobile patrol.
In 1921, Vollmer’s group of officers experimented with lie detector. Aside from that, they invented the first radio car with a crystal set and earphones. In 1908, August Vollmer discovered the idea of police school. It was formal training on how to become a police officer. It taught methods such as: fingerprinting, police methods and procedures, public health, sanitation, etc. While he ran the school, he tried to learn more about pharmacology and bacteria. After that, he became a full-time criminalist and was in charge of the criminal investigation lab. In 1923, he was highly sought after.
Los Angeles police fired rubber bullets Sunday into a crowd of people demonstrating against police brutality near the LAPD's downtown headquarters, breaking up an unauthorized splinter group of marchers who threw bottles, vandalized bus stops and yelled obscenities. In a scene reminiscent of clashes during the Democratic National Convention in August, police in riot gear fired the nonlethal ...
The Los Angeles police department wanted him to become chief. They wanted him to help turn around the city because there was so much police corruption, gambling, and prohibition. Vollmer turned the whole police department around by hiring people to replaces officers who failed intelligence tests. Vollmer also came up with the idea that police officers should serve as social works and not just arrest people. He wanted them to try to stop crime by “saving” the offenders. He wanted them to play an active role as a community member, too. His contributions are still very useful in policing today.
The idea of having a police school to develop the knowledge of future officers is used in today’s academies. Police cars are still used in police departments today. It makes use of quicker response to a call. Technology has helped Vollmer’s ideas develop to bigger and better things. He studied bacteria and pharmacology, now that stuff has developed so much, that they have advanced technology to find people’s DNA and place a person at a crime scene if they were part of it. Radios have developed so much that officers are now able to carry them without a problem. Technology now makes the radios clearer than ever.
