It's not really meaningfully different than existing closed-circuit cameras and bodycams, except for the ALPR plate/ID records they create, which states are simply going to exempt from FOIA, as Illinois did.
Sure. But until then, the US at large can hammer them to dust. And, I expect adding ALPR to an exemption was for simplicity's sake- since it's already general knowledge they don't have to create anything for a FOIA request. Easier to just make it explicit so they can point to the law/code.
