Do Blacks Really Commit More Crime?

I recently had a conversation with a friend about this subject and it really got me thinking. If you were to ask anyone in the United States this question they would say "yes" or "of course". And why wouldn't they? You see crimes committed by Blacks every where, on TV, the Internet, in newspapers, every where. So it would allow someone to think that Blacks are a race of criminals. Not only is it always in the media but some people would argue that statitics show that Blacks commit more crimes based on the prison population. That doesn't not mean they commit more crimes that may mean that the justice scales have been tipped not in their favor (Troy Davis). But, how can that be in a society where we are the minority? Let's say that White people are 80% (20 million) of the population and Black people are 12% (5 million) of the population. And statistics show that 40% of the Black population is in prison that is 2 million people and 40% sounds like a high number but it is only 10% of the White population. Although the percentage of criminals in the White population may be lower on paper but in reality they have a larger number of criminals, it is just because most of the time their crimes are not exposed unless it becomes too large to keep under a rug ( ex. Bernie Madoff, Jeffey Dahmer, Timothy McVey,and the list goes on).You have to be careful when dealing with numbers. Numbers can lie and numbers can be manipulated to anyone's benefit. We all know that every race has it's criminals it just seems that Black crimes are exposed more. Once I took the time to gather my thoughts, I had to ask myself...Do Blacks really commit more crimes? What do you think?
