Thanks for the comment, be careful not to confuse parallel constructions in writing with law enforcement 'parallel constructions' - that being said, there are some comparisons that can be made.

With a law enforcement PC, only those that have obtained the evidence illegally will know it's happening. The police force making the arrest (or traffic stop) that leads to the uncovering of the evidence that was originally illegally obtained may have No Idea, they're participating in a more complex targeting of an individual.

Hope that makes sense.
