The interpretation of "APACHE" that I like best is it is a taunt to Comey and the dark hats. They can talk in code, and so can Q. Think along the line of "APACHE" being white hat code for "activate sleeper cells."
One of Alinsky's rules is to have fun. I think Q is having fun.
I trust your analytical skills, sir. I'll go with your theory and keep the others on the back burner.
Am I doing Alinsky right?
