Perhaps it is naive, but I think the point here was that the police, technically and legally speaking, are much more restricted. As flawed as it is both legally and in actuality, police is still way more restricted and accountable than ICE is both legally and in actuality.

Agreed. Zero accountability is not equivalent to theoretically substantial, but poorly enforced by design accountability.
