"An attempt to rapidly deport twelve million people will also change everyone else. As Trump has said, such an action will have to bring in law enforcement at all levels. Such a huge mission will effectively redefine the purpose of law enforcement: the principle is no longer to make all people feel safe, but to make some people unsafe. And of course the diversion of law enforcement resources to deportation means that crimes will not be investigated or prosecuted. So some people will be radically less safe, but everyone regardless of status will in fact be less safe.
Such an enormous deportation will requires an army of informers. People who denounce their neighbors or coworkers will be presented as positive examples. Denunciation then becomes a culture. If you are Latino, expect to be denounced at some point, and expect special attention from a government that will demand your help to find people who are not documented. This is especially true if you are a local civic or business leader. You will be expected to collaborate in the deportation effort: if you do, you will be harming others; if you do not, you risk being seen as disloyal yourself. This painful choice can be avoided not at a later point but only now, by voting against mass deportations.
The attempt to deport twelve million people will likely generate some resistance. It is hard to imagine that every single person will willingly cooperate. Some will run, some will hide with friends; and, inevitably, a moment will arise when law enforcement will claim (truly or not) that an undocumented person used force in trying to elude deportation. This moment is not a side effect: it is part of the plan.
The deep purpose of a mass deportation is to establish a new sort of politics, a politics of us-and-them, which means (at first) everyone else against the Latinos. In this new regime, the government just stokes the fears and encourages the denunciations, and we expect little more of it. If Trump and Vance win, this dynamic will be hard to stop, especially of they have majorities in Congress. The only way to avoid it is to stop them in November with the vote."
As an American, and as a historian who writes about forced population movements, I believe that we are not taking the Trump-Vance deportation plan seriously enough.
