I believe, based on explanations that I have seen on the Q threads, that they had to wait until all of the players had committed the crimes and had implicated themselves. That way, the whole network could be taken down and not just some of the players.
I almost agree with you. I’m 99 percent there, but am holding out that last percent because I just can’t take another let down. And what makes sense with the theory you provided is the fact that they continue fortifying DC. What for? It makes sense if we are at war... So we wait and watch. From the start, I’ve held onto hopes for justice and good prevailing over evil.
