The Wikipedia article on the subject links to many different sources and their evidence.

This one seems to be a good enough summation: https://www.pbs.org/wgbh/pages/frontline/waco/topten2.html

People from the cult did survive, did do interviews, and even brought lawsuits. A large group was released before the fires and nine more survived the entire incident. So maybe you aren’t as familiar as you think? Furthermore, we already know more than enough about the cult from _before_ the incident. It’s pretty clear they are a nutty cult.

But, I suspect none of what I wrote above matters to you. You’ll probably still say that it’s a conspiracy and the group was a normal gathering of people, ignoring all of the evidence to the contrary. So I’m not even sure what I hope to gain from this response.
