Editing Signals intelligence (section)

==Legality==
Since the invention of the radio, the international consensus has been that the radio-waves are no one's property, and thus the interception itself is not illegal.<ref>{{cite web| url = http://www.itu.int/en/ITU-R/conferences/RRB/Pages/default.aspx| title = Radio Regulations Board of the ITU|website=www.itu.int}}</ref> There can, however, be national laws on who is allowed to collect, store, and process radio traffic, and for what purposes. Monitoring traffic in cables (i.e. telephone and Internet) is far more controversial, since it most of the time requires physical access to the cable and thereby violating ownership and expected privacy.{{Citation needed|date=August 2021}}
