The 24 hour warning, yeah, clearly to them but at the same time their fate is connected to our investigation so when/if something happens to them it carried right over to our discussions. In fact 24 hours have passed now so whatever was going to happen is happening now/could happen at any point now since that time limit is now gone.
I always assumed there would be multiple night raids all taking place at the same time in many different regions to prevent communication and coordination. So if that is true then I would expect it to happen very shortly, probably even happening right now or will tonight. Just speculation of course but night raids are how I would think it would occur and full scale round up would be prudent so none could get word and escape.
