Fear is a feeling, and I'm not sure what "very real" means, as if your feelings are matter of national importance. If someone commits a crime, then the people are justified in acting - in a proportionate, necessary way - through government. Otherwise, your fear is your problem. Maybe the homeless person is scared of you - after all, you can call the police and subject them to serious abuse.

I agree that it's an often implied issue, but I think the sub-subtext, the point of it all, is far more serious: whether you can do things to other people - via the state or personally - for arbitrary reasons. That is, whether people have universal human rights. That is the elephant they are hunting.

They have found their best test cases, their best steps toward destroying universal human rights, with homeless people, people without legal immigration status, and those engaging in progressive protests.

They won't stop there, of course. It's either human rights for all or for none.
