SUBREDDIT: r/AskReddit
TITLE: Hey reddit ... want to help solve a mystery?
POST: A filmmaker friend is doing [a documentary on the Daniel Berrigan affair] a fascinating point in history, and a story with tons of local ties here in Maryland. The gentleman in question, Boyd F. Douglas, Jr., had a ringside seat to the proceedings and his perspective could help ensure the full story is told. I know without question that if he'd rather not participate, the filmmakers would step back and let him be. They'd like to offer that choice to him directly. Thought the power of reddit might be helpful in their search. Not looking for anything to be posted here ... anything relevant can go directly to the filmmakers at the email address in the [blog link]  Thanks for checking it out.
TL;DR: 
Help some honest filmmakers find a helpful witness to history, if you can. If not, click the link, read a little, and keep your eyes peeled for a well made, thought provoking documentary.
