I forget the title, but after Waco the Treasury and Justice Departments’ did a pretty through after-action investigation and published a 400 page or so report that should be available through the Government Printing Office and is probably at your college library.
And there are non-government sources presenting very different views of what happened at Waco. A check of Amazon.com, publishers such as Paladin Press, the Library of Congress website, and such should give you plenty of leads.
Proper scholarship requires you to read and evaluate a variety of sources and draw your own conclusions.
Don’t let anyone else tell you what to think – and definitely don’t read only those sources that tell you what you want to hear.
