I ham a ham radio license and should probably know this stuff, but I don’t play near the edges where I’d ever need to worry about the details. It seems nuts to me that it’s illegal, anywhere, to notice what radiation (technical sense) is around me. “Hey, watch out, in Kentucky it’s illegal to see orange” is about as logical as anti-detector laws. You’re pointing an emitter at me and I’m not even allowed to know? That’s crazy.
Morally, I agree 100%. But legally, detection is banned in some jurisdictions (Virginia, Washington DC, most of Canada, etc.) so it's ambiguous to say "we have a right" without at least defining which population and which definition of right.
I accept these definitions. But undefined, readers could be very confused thinking that specific jurisdictions and/or legal rights are being discussed.
It's no different than sight, just in a different wavelength.
It's what we choose to do with that knowledge is the subject of the law.
We have a right to detect what is bring radiated at us.
