Moves and counter moves. Do you really think it was a good idea to give such advanced notice that roundups were coming? All the way up to saying early Sunday morning? Think. The people that are going to be targeted were closely monitored and likely gave away locations of hidey holes, routes to be taken, all sorts of their counter measures. The admin of these cities involved were monitored to expose their plans to obstruct/disrupt as well. Don't think that is valuable intel? This is a LONG game. When Dems don't reach an agreement the raids will commence at at break neck speed. It won't only be immigrants being rounded up either. This will be the largest sting in history when this is over.
Good luck anon. Thanks for doing your part.
