ICE, and the current leadership, has to accept some responsibility here. The entire campaign was not thought out. It is mere show, cosplay, what did they expect was going to happen.
First off, like it or not, schools, churches, and courthouses were off limits. There are good reasons for that, but it was ICE that broke that rule. They have to take responsibility for the blowback. And there can be no doubt, this administration is purposely avoiding due process and they have no problems denying due process to citizens if it serves their purpose. Again, the responsibility lies with the administration, because again, it was fully predictable blowback.
