I'm pretty sure Intelligence types say the absolute minimum to politicians already. The trouble is, politicians are on top. When they ask a question, Intelligence is supposed to answer.
Supposedly, the briefing that politicians get is stripped of as much information as is safe to do to protect people and methods from politicians getting pissed one evening and telling everybody everything.
ie this "Our spy $name placed in $department tells us that they plan to do $thing on $date"
gets stripped back to something like this:-
We have information that $who will do $what on $date. We are highly confident of this information.
Now if the opposition knew that then they might be able to figure out ways that the information might have been gained back to a person or method, but there is a balance between a need to know the information, and having the information and not sharing it (at which point having gone to the trouble and expense of getting the information is wasted)
