My advice, after seeing dozens of letters to the editor, papers, and essays on this issue posted to all kinds of gun forums, is simple.
Just because you're right doesn't mean you can scrimp on the evidence, writing, or logic.
Things that we take for granted as first principles (i.e. something that is self-evidently true) are not always seen the same way by other people.
This means that you must provide the logical chain of your position, not simply make bald assertions that would go well in signature lines on this forum but have no place in academic writing. You must use peer-reviewed sources for your paper, not something you found on some guy's web page on the internet (Note, you can use the internet to find these sources, but if you're going to cite something, it's more credible if it's original research, not something that someone with no credentials says about someone else's research).
Also, don't make wild claims that your research can't back up.
It may seem self-evident to most people on this forum that shall-issue concealed carry laws have a negative effect on crime, but the research about this is not that ironclad, and there are a lot of factors that go into it.
Lastly, remember this maxim of persuasive academic writing or speaking-
CORRELATION IS NOT CAUSATION.
