Thanks Ron. I was not aware that any "real" research is done when one applies. I know that we gave references, but was not aware of references being called. Of course as an Eagle, I never thought they needed to do research on me, but maybe they did. (The FBI background investigation I needed for my job was probably more complete.)
As of April 1 of this year, the BSA has hired a company whose name I forget ("Check" something, I think) to run a nationwide check on every leader who files a Adult Application. That includes currently registered leaders who are switching to a new position (e.g., from Webelos Den Leader to Assistant Scoutmaster). If you show up with a conviction anywhere in the U.S., there should be a hit, and then it depends on what your conviction was for.
