You have two paths - one is to use internet sources like guncite.com or original scholarly sources.
Look for Kleck, Lott (pro) Wintemute and Cook (concealed carry stinks).
Don't plagarize - so easy with online sources. Does your prof want a researched piece with empirical evidence or will just various opinion rants be enough?
Give me an acknowledgement as a consultant. Or you can get a guy in Nigeria to write it.
