There are more than 780,000 police officers in the United States. Everyday, these brave men and women put their lives on the line for a thankless but highly necessary public service. Police officers serve their communities selflessly; they deserve the very best. However, recent high-profile cases that have grabbed national headlines have raised tensions between police departments and the communities they serve. Tragic cases of police brutality and excessive use of force have inspired outrage in all corners of the country. Police departments are struggling to find ways to restore their public image. Various methods and solutions have been proposed to combat the issue, such as increasing transparency between the police and the public.. One proposed solution to the current controversy is requiring police officers to wear body cams on their persons. Trial programs in Los Angeles and Baltimore are underway, among many other cities. Body cameras for police officers are showing some promise. Body cameras, after all, come at the heels of another kind of police surveillance already in common use: police car dash cameras. About 72% of state police departments and highway patrol vehicles already use car dash cams. Police departments find them useful for several reasons. First, these cameras offer direct evidence of everything a police officer and an assailant does while in front of the car. This is a very useful tool for police officers in terms of providing evidence of what happened. Police departments use the footage to review procedure, identify what a police officer does right and potentially what he or she does wrong. This footage is used for current officers as well as in-training officers for training purposes. There are a number of other positive reasons for the use of car dash cams. Each one of them are geared toward the safety of both the police and the people they serve. For more information about these cameras, feel free to leave a comment or question at the bottom.
