Maintaining secrecy?

[AGDem]

Recently, someone I know in a fraternity at another school said that he knew the secret handshake to another one of the national fraternaties on his campus and was actually able to show it to me. When I asked him how he knew, he said that he knew a guy who had transerfed to his school, and at his old school he was a member of a certain fraternity and had no regard for the secrets of his fraternity and disclosed their secret handshake to my friend. I don't believe that this other person fell in with the chapter of his fraternity at his current school, although to my understanding he is still a member.

Now, I don't believe for a second that certain secrets of fraternities or sororities haven't gotten out to non-members in the past, and I'm sure that that has only happened in rare cases. But it still remains that our organization's secrets are part of who we are, and without them our organizations loose part of our identity.

And oppinions on the matter? Can those who may disclose secrets be weeded out before it's too late? Or is secrecy not as important of an issue as some people make it out to be?
