Most law enforcement actions are predicated on circumstantial evidence.
We already provide such information, which is completely legal.
For instance, if there's a pipe bomb, police track down the list of people who've bought ingredients from the bomb (from retailers, cell phone companies) and other sources of information to narrow down the list of probable suspects.
The Boston bombers were caught by such techniques. I don't see why this is any different.
It's different because this isn't the government doing it. It is corporate vigilantism at best, which means there is no oversight and no privacy.
Regardless, your reframing is not convincing. Portraying immigrants as "criminals" isn't gonna make people want to deport them any more than saying drug users are inherently criminals. The reality of the law is way less important than its actual morality, which people have made up their minds about already.
Palantir is a company selling data analysis software. They're doing what they're paid to do. How is this corporate vigilantism?
> The reality of the law is way less important than its actual morality
That is absolutely untrue. There are ways to change the law. People fail to understand that when you break the law to protest it, you still have to face the consequences.
This latest federal judge injunction against the travel bad is a horrible thing for our system, no matter what you think of the ban.
The president is well within his purview to establish regulations and restrictions for foreign travel. For an activist judge to make a decision like this, gives ample reason for his removal and/or sanction. Once you have the judicial branch trying to enact policy or morality, you have the ability for the executive branch to remove all dissent.
The immigration act makes it explicitly illegal to discriminate based on religion. That act is instructions to the president from Congress. The president is banning travel from those countries for their religion. The president absolutely does not have the power over foreign travel you say he does, that belongs solely to Congress. You're delusional.
