According to User:Kosebamse the following is from a Wikipedian IRC thread:
Raul654: oh, and snowspinner, I've come to a conclusion
Raul654: making policy on wikipedia is hard
Raul654: because there are people who oppose any common sense measures
JamesF: Raul> Indeed.
Snowspinner: Yes. I came to that conclusion as well.
Raul654: I have decided that it's better to shoot first and ask questions later ;)
Snowspinner: I'm in that camp too now.
Raul654: don't worry about making common sense policy
Raul654: just do things with common sense
Raul654: and wait for policy to catch up
This exchange has been widely quoted throughout the web at least since 2005.
Raul654 (Mark Pellegrini) is a senior member of Wikipedia’s Arbitration Committee. According to WikiTruth, "Philip "Snowspinner" Sandifer is a Ph.D. student in English, specializing in comics studies, at the University of Florida, and a managing editor of ImageTexT, a peer-reviewed journal devoted to the study of comic strips and animated cartoons."
