I am writing a research paper on "The Death Penalty" and how capital punishment is unfairly given to minorities but I don't know where to...

There is a wealth of information about the death penalty,
whether it is effective as a deterrent, and whether it is fairly imposed and
administered. There are many web sites that advocate the moral and/or religious points
of view, both for and against, but my answer focuses on resources dealing with the
legal, political and social aspects of the death penalty.

I
suggest you start with a source that collects and analyzes data regarding the death
penalty, how it is imposed and on whom.  A good starting point would be the Death
Penalty Information Center, a well-respected non-profit organization that has been
studying the death penalty in the U.S. since the early 1990s.  The Center's web site is
at

http://www.deathpenaltyinfo.org/home

Another
web site that addresses the death penalty issue, its effectiveness and fairness
is:

http://bpp.wharton.upenn.edu/jwolfers/DeathPenalty.shtml

This
web site has links to pdf files of various articles describing research on the death
penalty, its effectiveness and fairness of its imposition and
administration.

Two other online resources you should
investigate are the ACLU Capital Punishment
Project:

http://www.aclu.org/capital-punishment/aclus-capital-punishment-project

and
the NAACP web
site:

http://www.naacp.org/advocacy/deathpenalty/

One
last group of web sites worth viewing are the Innocence Project web sites.  There are
Innocence Projects in many states, e.g., Illinois, Texas, Florida, Georgia, etc.  They
are non-profit legal organizations that offer legal representation to persons who have
been sentenced to death. Death penalty appeals require an exceptionally high degree of
skill and expertise that court-appointed attorneys in many states often lack.  The
Innocence Project web sites are well worth reading to find out about the issues of the
fairness of the imposition and administration of the death penalty. Just "google"
innocence project, and you'll find many of these
organizations.

Finally, you will also find a lively debate
in the pages of the New York Times and on web sites of organizations such as Amnesty
International.  Amnesty International opposes the death penalty, but you can find other
sources of information in the articles on the site.  The New York Times has vast
archives that will provide you with a great deal of factual information and debate on
all sides of the issue.

The sources I have described above
should be enough to get you started on your research. During the course of your
research, you will no doubt find additional sources of data and
debate.

Good luck!
