Why Do Police Abuse Their Authority?

There is No actual answer to why they do it. But what can be said is that many civilians are tired of it and want it to stop. Many civilians came out to rally against the Kentucy Police Department after they shot and killed an African American male by the name of James Taylor. He was shot 11 times while he was in handcuffs in February 2003. Police tend to get away with things such as this because those who are apart of the government is to weak to take a stand. There are many cases where Police Officers have shot and killed innocent people and are easily acquitted. So There is the answer I guess. They abuse their authority because there isn't anyone powerful enough to convict them.
