That's an interesting thought. Some terrorist is in the US and planning something, but they don't want to give away their intel. So do a bit of parallel construction and tip off the local cops to some relatively small crime he's committed in the course of everything....
Or substitute "whistleblower" or "inconvenient politician" for "terrorist" if you prefer.
I didn't downvote you, but I expect those who did aren't reading it as "a question" as in "a request for information" - which I would think should rarely be downvoted - but as "a rhetorical question" whose purpose was to serve as a point of argument. Interpreted that way it seems to be attacking a strawman, poorly - such a comment would be deservedly downvoted.
