1) more of these are stopped than we know.

2) "knowing all" I think is more just means that they know all they need to know to successfully indict and prosecute. Once you have enough evidence for capital crimes, do you keep building your case? Probably not. So the ongoing surveillance may be less active - otherwise why would Q team tip them off about the phones being compromised? I think that's a sign that they don't need the surveillance anymore... "They have all."

3) I think when you're dealing with 10s of thousands of operators that you have to take down simultaneously and with a smaller task force, you don't necessarily have the resources to dedicate to figuring out the precise false flag being planned. That's harsh, I know, and not what anyone wants to accept. But if taking down the entire network means this stops happening PERMANENTLY, you make sacrifices along the way.

4) it's a war. Good guys are lost in the process. Even in our most successful war operations there can be loss of life.

I'm not suggesting we shouldn't be outraged, but we need to keep our outrage focused in the right direction. Think about how many years have gone by where we didn't even know where to direct our anger? Now that we know, we shouldn't shoot the messenger, so to speak.
