Stop killing each other where's the peace

why do people kill is it because of race or how one dresses i want to know there are cops killing colored men for what because the color of there skin. I don't get it i think that we as a people should come together because at the end of the day we are all the same we screw up we get into things the only thing that has changed is the color of our skin. another reason you should sign is because i want violence to stop why do we kill each other what does that solve where does this get you besides in jail and maybe dead depends on who your dealing with but there are so many deaths i think people should stop killing each other join together and progress as one
