the tactics used are exactly the same as how the ridgeway moots in SE England would get closed down every so often, and some of the callsigns used (Bronze, Silver) show that the rave is being considered as major incident (same as terrorism etc)
Airwave is (unfortunately for ravers) very effective as a voice comms system (despite the rubbishing it got in the IT press), their old analogue radios used to be plagued by interference and pick up foreign TV soundtracks and I’ve known cops to abandon closing down a party simply due to comms problems..
