Compliance To Police and Police Accountability ?

As a 49 year old Black Man, my experience dealing with Police are mixed because I was taught to always comply with them out of respect, not because I feared for my life. Most of my inter actions with them have been peaceful but there are several times I have run in conflict with them ! After 9-11, I was jumped by four under cover Police men because of my Islamic last name in a southern state . I believed they would of killed me if it was not for GOD sending this old man out of his house, turning on his house spot lights. I defended my self and broke a officer jaw in the process according to them, but they jumped in there white unmarked and sped off ! I had to leave this Southern state for fear of my life, but even though this happened to me I never felt hatred for Police in my heart, I live with my 5 fractures. I also remember being 16 years old riding through a " European American " neighborhood at night with other Black friends as my self, being pulled over IDeed and asked real nasty by a drunk cop, " Why are you " NIGGERS " in this neighborhood ? I felt fear in my heart but he let us go ! And also I had a business conflict with a major casino mogul out here in Las Vegas in 2002 and he had people follow me and a under cover cop pulled up to me and pointed his fingers like a gun to the side of his head and pulled an imaginary trigger ! Needless to say, I reported this incident to a US ATTORNEY and ever since then I never had a problem with Police again ? MY point is, if bad Police are never convicted and sent to prison for there abuse and deadly force, then nothing will change with out a " Police Man " being made as an " Example " !
