I would define police brutality as something that occurs when a police officer acts with excessive force by using the amount of force with regards to a subject that is more than necessary. By excessive force, I mean that the officer use more than the amount of force to get the subject under control. I feel that police brutality happens when an officer has the subject under control and then might hit the subject with a black stick, or use the taser gun on the subject. When trying to get a suspect to comply with orders given by an officer, the amount of force should be used in only the minimum amount needed to gain control of a situation. Police brutality is a direct violation of the laws within the police force. This is a form of police misconduct.
The relationship between police brutality, police corruption, and other police misconduct falls all together. By this, I mean that they are all in direct violation of the laws. The relationship between the three is that they are abuses of police authority. Police corruption is the abuse of police authority for personal gain. Corruption might involve any type of material benefit gained illegally by an officer because of his authority. Forms of corruption could include anything form bribery, extortion, selling drugs and many other things. This is also considered a form of misconduct.
I would recommend that the police officers who are found guilty or involved in any of these type of actions be handled with the highest actions necessary to assure that it does not continue to happen. By this I mean, strengthening police leadership, develop clear written debt policies and procedures so that it is known by all officers that this type of behavior are not acceptable.
