oral on racism and racial homicide! HELP!

[Black Cat.1]

hey guys, i was just a little confused about how to tackle the oral.... i dont know what the bulk of my presentation should be on, and i seem to be having a small case of writer's block...  any suggestions about what to include in the main body paragraphs?
my main contention is gonna be along the lines of : racism is inhumane and the prejudice causes strife in society and divides social groups. we must omit this trait if we want to progress as one. thanks for the input!

If you're looking for a divide among social groups: the recent shooting of Treyvon Martin is a good one.

yeah ive oriented my oral around that case actually, its what motivated me to choose this type of topic actually. ill probably use it to consolidate ideas and for cutting-edge proof that we really have regressed and that racism is deadly... but i dont really know how im gonna structure my oral....
I want a sort of intro -> 4 body paragraphs -> conclusion set up, but i cant seem to think of 4 ideas to discuss in my presentation
