In the same way that not everything police do is legal, sure. But the majority of what they're currently doing is legal, and it's their job. Of course we should take steps to address the illegal things and prevent them from happening, but we should still recognize that the overwhelming majority of it is the exact same thing they've done under different administrations.
I get civil disobedience. But I end up stuck when the disobedience is taking the form of actively obstructing law enforcement. If this were police doing their job to apprehend a suspect in a criminal investigation, I can't imagine so many people would be sanguine about organized groups of people assisting the criminals in evading the cops. And that's what's happening here - it's not just people protesting ICE, it's people actively and intentionally helping illegal immigrants evade ICE. And that's before you add in the vandalism, harassment, and intent to doxx agents and their families.
