Cheng asked: If you developed your potential agent with your commercial cover, why and how do you change your cover for recruiting?

You can spot, assess, vet and develop a potential target of interest using your true name NOC commercial cover but that's as far as it goes - in true name. For recruitment and handling, the target must be turned over to a second Case Officer, usually in an operational alias. This is usually done in either an "attributable" or "unattributable" spinoff. In an attributable spinoff, the target may realize some connection between the first and the second Case Officers. In an unattributable spinoff, the target does realize any connection between the two Case Officers. Unattributable spinoffs offer the most protection for the true name NOC Case Officer. We will get into this in much more detail in a later posting. Just keep checking the blog now and again. I'll admit that I once handled an agent for many years in alias but on an occasion I was able to visit his research lab using my true name NOC cover and he happened to learn my true name and my commercial cover, as well. Being an old pro who had worked for the Company for many years, the security risk to me and my cover was deemed minimal.
