Specific people are named in the mind map (i.e. Jens Ludwig and Roseanne Ander). These people are not to be found, by my searching, on the accompanying source. That's a WP:Verifiability and WP:BLP issue, and that's why this is also WP:OR. How do we know these named individuals have anything to do with the Joyce Foundation or gun control funding? We don't, because there's no source that says so.
