Police Brutality

So if you've read my first post,  I was in the midst of choosing a theme to write about for my English paper this semester. I did end up choosing police brutality as my theme because it is interesting to study. Also, because I am majoring in psychology I will be taking the psychological aspect to this and study why policemen may exert brutal physical harm to their criminals. Some questions to start my research:
How much stress is the average police officer able to endure?
What other stressors impact the officer other than the obvious work related stress?
How could an officer cope to these stressors instead of expressing them though their job?
Why do they actually feel as though it is okay to exert this over the top brutality?
Police brutality is very important and has been a hot topic on the news lately. Many teenagers and young adults find this wrong and believe it is happening more often now-a-days then before. The case of brutality strikes us humans as morally wrong (well. . . because it is), but most people just see the actual violence. Not many understand why this happens, and I find it important to educate people of the terrible wrongdoings and also help them understand how and why it happens.
Police brutality is clearly a disturbing part of enforcement, but what exactly brings a police officer to exert this kind of violence and how could we possibly tone down this brutality?

Myself

Hi, my name is Amber Danielle Scull. I am currently a sophomore student enrolled at West Texas A&M. This is actually my first year at WTAMU. I went to the University of Florida for my first year of college and it was absolutely amazing. It was great to be a Gator (I still consider myself one). Certain reasons brought me back home, though, and things are going well for me here too. My major is in psychology as of right now, and I plan on double majoring in criminal justice. However, I just recently became incredibly interested in forensic pathology, which is basically a medical examiner who examines dead bodies of those who died suddenly, unpredictably, or violently and determine the cause of death. I was born in Hampton, Virginia on a naval base as a result of my parents meeting in the Navy. We shortly moved to Amarillo, Texas where I have spent the rest of my life. I was raised by the most perfect dad who introduced me to many of the things I like and shaped me into the person I am today.  I enjoy music, food, reading and watch television series. Some current ones I'm in to at the moment are Chuck, The Walking Dead and American Horror Story. I'm also currently in to the television show Cops. This brings me into a topic that spikes my interest: cops mistreating suspects for no reason or overstepping boundaries to control a suspect. This might become a focus point for all of my English papers for this semester.
