If they know you're trying to shake them, that alerts them and eliminates any opportunity you might have otherwise had to feed them misinformation in the future. Or, depending on the potential threat you represent, they might just arrest you and put you in a dark hole since you're obviously no longer a useful source of intel. -- That woman deserves her revenge, and... we deserve to die. -Budd, Kill Bill

Coventry. Story goes Churchill had info from Bletchley Enigma intercepts that Coventry was next to be bombed, but if he evacuated it, the Germans would have suspected that Enigma was cracked. I've also heard references that this was an urban legend, not sure. However, they did sink quite a lot of subs based on triangulation + Enigma decrypts by fortuitously sending an airplane in the area they knew the subs would be before hunting them down - as cover to say that the subs were spotted... This way they could sink the subs and still let the Germans think that Enigma was safe.
