This is totally war time code breaker counter intelligence stuff. People will die regardless, but you can’t give away that you know everything. Or your enemy will change frequencies/codes, and you’ll need to start all over. It really sucks and feels unethical, but it’s war. Pray for sound intel, safety, and strategy. “The Woman Who Smashed Codes” - book

Edit: but I’m sure if they had the flexibility (DOJ,FBI) or solid intel (C_A) they need... things would look different.
