Comments: Al Qaeda's use of cryptography - scant evidence

Sigh,

Law enforcement investigations are first and primarly interesting in traffic analysis. Not content.

"Code book" cryptography is virtually unbeatable because of its low redundancy. Ample examples of the troubles with "code book" crypto can be found in Khan; Trouble for their users as well as for their cryptoanalysists.

So hidding your trail provide better protection then flagging communication to be "encrypted".

Maybe, just maybe in an open society it doesn't matter who you are talking to. And, what you are talking about does matter.

But, in the murky waters of criminal organisations, who you are talking to does matter. And criminal investigators now that.
