I think that's the million dollar question for the IRB. It's very difficult, because Falun Gong is a spiritual belief. It's a belief system. You believe it. It becomes part of who you are. But there's no membership. There are no rituals. There's no worship. It's a belief. So what we try to do is give the IRB some information based on our personal expertise of who we feel the Falun Gong practitioners are, because we are the ones who are involved in the Falun Gong community day after day. Through their sharing, through their history, and also through their involvement in the community we can verify if they are true practitioners or not.
